(c) Oval Red Blood Corpuscle.
Explanation:
Camels are adapted to desert life and can survive for long periods with little water. One crucial adaptation is the presence of oval-shaped red blood corpuscles (RBCs). This shape allows the camel’s RBCs to circulate easily even when blood becomes thick due to dehydration, and the RBCs can expand more than other shapes without bursting, helping the animal recover swiftly after drinking water again.
