Question

Which one of the following feature is common in silverfish, scorpion, dragonfly and prawn?

• A. Three pairs of legs and segmented body
• B. Chitinous cuticle and two pairs of antennae
• C. Jointed appendages and chitinous exoskeleton
• D. Cephalothorax and tracheae

Answer 1

The correct option is C Jointed appendages and chitinous exoskeleton

Silverfish, scorpion, dragonfly and prawn all belong to phylum Arthropoda. All arthropods are characterised with jointed appendages and a chitinous exoskeleton. The exoskeleton helps in protection. They shed their exoskeleton by a process known as moulting or ecdysis.

So, the correct answer is option C.
