Identify the figure from below given options, which could replace the sign ‘?’ to complete the series of figures:

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →


The series repeats every four figures, since the fifth figure is the same as the first. At each step one of the two lines moves its slanting end to the other side, the lower and the upper line in turn, and the corner shape turns half a round after every two figures. So the fourth figure keeps the corner of the third (open at the bottom left) and has the upper line’s slant on the left and the lower line’s on the right.
