Answer :

Q)

Correct choices B C D

Thoracic breathing in reptiles.

Water tight skin.

Have amniotic eggs.

Cutaneous respiration is for amphibians. In reptiles its exclusively thoracic. This helps them to perform more on land.

Their water tight skin with thick keratin and scales prevent water loss.

Their amniotic eggs also prevent water loss from egg. They have internal fertilization which also helps in land life. Amphibians have soft eggs. They can only be layed in water. Reptile egg shell are strong and good for land life. Certain reptiles give birth to young ones.

Also reptiles are ectotherms. Reptiles donot undergo metamorphosis. All this are better adaptations for land life than amphibians.
