• A. A-III, B-IV, C-II, D-I
• B. A-III, B-V, C-I, D-II
• C. A-II, B-I, C-V, D-III
• D. A-IV, B-III, C-II, D-I

Hint:

In non-crocodilian reptiles (like lizards and snakes), both left and right systemic arches are present, but the temporal fossae are key features used for classification (Diapsid skull).

Answer 1

The Correct Option is B
