Show answer & explanation
Correct answer: C
Compare the boundaries of the given part in Panel I with the candidate pieces in Panel II. The required second part must fill the white stepped cut-out exactly so that the two pieces together form the original square PQRS.
The missing outline has one vertical projection and one horizontal stepped projection arranged in the same orientation as shape (iii). Shapes (i), (ii), and (iv) either place the projections on the wrong side or form a mirror orientation that will not fit the gaps in Panel I.
Therefore, the other part is shape (iii).
