Solution

The correct option is B Tentorium
The tentorium is the internal skeleton which gives strength to the head capsule and provides a place for muscle attachment. It is formed by tube-shaped inward extensions of the exoskeleton. The mandibles, maxillary and the labia papillae are all visible. Hence tentorium plays an important role in the growth of the exoskeleton.
So the correct answer is 'Tentorium'.
