Choose the colour that should replace the question mark. 
1) Read the two progressions on the top strip.
The left trio goes yellow $\to$ yellow-orange $\to$ orange. Hue shifts from about \(60^\circ\) (yellow) toward \(30^\circ\) (orange) with lightness roughly constant and saturation increasing slightly.
The right trio goes peach $\to$ pink $\to$ magenta. Hue shifts further toward \(\sim310\!-\!320^\circ\) (magenta), while value/saturation also climb (the last swatch is the deepest/most saturated).
2) What must the missing chip be?
It must bridge the end of the first trio (a medium orange) to the start of the second trio (a light peach). That means: Hue: slightly cooler than orange but warmer than pink — i.e., a peach/apricot in-between. Value (lightness): closer to the lighter right trio (to avoid a jarring jump from medium orange straight to a deep pink). Saturation: moderate — not as saturated as orange (C), not as saturated as pink/magenta; slightly desaturated like a pastel.
3) Eliminate the options.
(A) and (B) are already on the pink side (too cool in hue), so they do not bridge orange$\to$peach smoothly. (C) is a saturated orange—it does not move the hue/value toward peach/pink and produces a saturation spike. (D) is a light, slightly desaturated peach, exactly the needed intermediary in both hue and value.
[2pt] Therefore, the missing swatch is \(\boxed{(D)}\).

Shown below are three types of interlocking rods. There are in total 12 rods: 6 of type A (8 cm), 2 of type B (5 cm), and 4 of type C (4 cm). What is the maximum straight length obtainable by connecting the rods appropriately?
