Answer 1

The correct option is B

Feeding habits

The nature of the digestive tract in different vertebrates vary based on their eating habits. For e.g. cows have a ruminant stomach which inhabits methanogen bacteria which help them digest cellulose present in leaves of the plants. Human beings cannot digest cellulose as they don't have a ruminant stomach.
