Solution

The correct option is C

Because the skeleton is on the outside


Cockroaches have exoskeleton made up of chitin.

When a skeleton is on the outside, it is called an exoskeleton. The exoskeleton supports and protects the roach’s insides. Because it is hard, the exoskeleton cannot grow. The skeleton is made of a hard substance called chitin.
