Question

Which one of the answer figures complete the sequence of the problem figure ? Select the correct one.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Between successive frames the whole content turns 90 degrees clockwise about the centre where the four small squares meet.

Answer 1

The Correct Option is D

Each frame is a 2 x 2 arrangement of four items around a common centre: concentric arcs, a half-black square, a black wedge and a line ending in a circle.
From frame 1 to frame 2 and from frame 2 to frame 3 every item moves one cell clockwise: the arcs go top-left, top-right, bottom-right; the half-black square goes top-right, bottom-right, bottom-left; the wedge goes bottom-left, top-left, top-right; the line with circle goes bottom-right, bottom-left, top-left.
The circle at the end of the line alternates between open and black (open, black, open), so it is black in the fourth frame.
Hence the fourth frame has the arcs in the bottom-left cell, the half-black square in the top-left cell, the wedge in the bottom-right cell and the line with the black circle in the top-right cell.
Options (3) and (4) both have this placement, but option (3) shows five concentric arcs and a longer wedge, while the frames of the sequence always have four arcs.
Answer: (4)
