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.
