Solution

The correct option is D Antennae
Cockroach antennae have been extensively used for studying the multifunctional sensory appendage that generates the olfactory, gustatory, tactile, thermal, and humidity senses. The tactile sense is thought to play a key role in perceiving physical objects. Because most cockroach species are nocturnal, the tactile sense of the antenna would be essential to determine the position, shape, and texture of surrounding objects in the dark.
So the correct answer is 'Antennae'.
