When a pattern has multiple elements changing at once (like color and shape/position), analyze each element's pattern separately. Then, find the option that correctly continues all the individual patterns simultaneously.
Step 1: Understanding the Concept:
This is a pattern completion problem. We need to analyze the sequence of colored blocks with a wavy dotted line and determine the next block in the sequence that should replace the question mark.
Step 2: Detailed Explanation:
The pattern has two components: the background color and the position of the white wavy line.
The Color Pattern:
The colors in the vertical strip progress from top to bottom: light green, dark green, light blue, dark blue, lavender, light purple. This is a sequence moving through the color spectrum (Green → Blue → Violet). A logical continuation of this sequence would be to loop back to the beginning of the spectrum, starting with Red/Pink. Options A and B are pink, making them strong candidates based on color.
The Wave Pattern:
The white dotted line forms a continuous sine wave that is moving vertically down the strip. Let's track the position of a feature, like a trough (the lowest point of the wave).
Top green block: Trough is in the upper half.
Second green block: Trough has moved down to the middle.
Top blue block: A peak is now in the upper half.
Second blue block: The peak has moved down.
Lavender block: A trough is now in the lower half.
Purple block: The trough is almost at the bottom edge.
The wave is clearly progressing downwards. After the trough in the purple block moves out of the frame at the bottom, the next part of the wave to become prominent would be the following peak, which would appear in the upper half of the next block. We need to find an option that shows the next phase of this downward-moving wave.
Evaluating the Options:
We have determined the color is likely pink (Options A or B).
Now we check the wave position in A and B.
Option A (dark pink): Shows a trough near the top. This would be a plausible restart of the cycle.
Option B (light pink): Shows a peak in the upper-middle part of the block. This is a very logical continuation of the wave's downward movement from the preceding blocks.
Combining the two patterns: The color sequence Green → Blue → Purple → Pink and the wave's continuous downward motion strongly point towards Option B.
Step 3: Final Answer:
Option (B) correctly continues both the color sequence and the pattern of the moving wave.

Approach Solution -2
Treating the wavy line as a single continuous sine wave running down the whole strip, each block covers a fixed slice of the wave's cycle, so working out which quarter-cycle the missing block should show, and checking that against the colour rotation separately, narrows the four options down fast.
Option A: the colour is a plausible next shade, but the wave in this block sits at the wrong phase, roughly repeating the phase already shown two blocks earlier instead of advancing to the next quarter of the cycle.
Option B: the colour continues the green, blue, purple rotation into pink, and the wave sits exactly one quarter-cycle further along than the previous block, continuing the steady downward drift seen throughout the strip.
Option C: breaks the colour rotation, since its shade does not fit where the spectrum sequence should be at this point in the strip.
Option D: keeps a colour that does not match the expected point in the green-to-pink rotation and also shows a wave phase that jumps backward instead of continuing to drift down.
Only Option B keeps both the colour rotation and the wave's phase advancing exactly as they have through every earlier block.
