• A. A- (i), B- (ii), C- (iii), D- (iv)
• B. A- (ii), B- (iv), C- (i), D- (iii)
• C. A- (iv), B- (iii), C- (i), D- (ii)
• D. A- (iii), B- (i), C- (ii), D- (iv)

Answer 1

Answer: (B)

The compound eyes of arthropods like insects, crustaceans are composed of units called as ommatidia (so, responsible for vision).
The trochanter is an anatomical part of the femur connecting to the hip bone.
The coxa is often in the form of a truncated cone and articulates basally with the wall of the thorax.
A sclerite is a chitinous or calcareous plate or similar part of an invertebrate, especially one of the hard outer plates forming part of the exoskeleton of an arthropod.
Therefore, the correct answer is option C.
