Answer

A

Explanation

The characteristics possessed by aves are as follows
These are warm-blooded animals having four-chambered heart. Their body is divisible into head, neck, trunk and tail. These are flying animals, having exoskeleton of feathers. They have modified forelimbs into wings and jaws are modified into horny toothless beak.
Their bones are light in weight because of air spaces (pneumatic bones) and the body is streamlined to reduce air resistance during flight.
Lungs as well as air sacs are present for double respiration.
