In which of the following option figures is figure (X) hidden as a part of its lines? (Rotation is not allowed.)

Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →

Figure (X) is made of 6 straight lines. Look for the same shape, in the same size and the same way round, among the lines of each option. It can be traced in Option (4) (green lines below); the other options hold only a changed copy of it.

Option (1) — Incorrect. It contains a shape like (X) in which one line points in a different direction, so (X) cannot be traced.
Option (2) — Incorrect. It contains the shape of (X) turned through 90° anticlockwise (a quarter turn), not (X) as it is given.
Option (3) — Incorrect. It contains a shape like (X) with one of its lines missing, so (X) cannot be traced completely.
