Solution

The correct option is B Diapsida
Diapsids are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls. Diapsids are traditionally classified based on their two ancestral skull openings posteriorly above and below the eye. This arrangement allows for the attachment of larger, stronger jaw muscles and enables the jaw to open more widely.
While synapsids lack the openings or fenestrae in the temporal region of the skull. Synapsids possess a single lateral opening in the temporal region of the skull.
So, the correct answer is option A.
