Solution

The correct option is D First pair of legs
  • The thorax of the cockroach is divided into three distinct segments: the prothorax, mesothorax, and metathorax.
  • Each segment of the thorax bears a pair of walking legs. Thus, the first pair of legs arise from the prothorax.
  • The first pair of wings arise from mesothorax and the second pair from metathorax.
So, the correct option is B.
