• C. i – frog, ii – pigeon, iii – star fish, iv - Nereis
• D. i – Frog, ii – Parrot, iii – Lizard, iv - Earthworm

Answer 1

The correct option is D

i – Frog, ii – Parrot, iii – Lizard, iv - Earthworm

(i) Cold-blooded (poikilothermous) animals, i.e., they lack the capacity to regulate their body temperature like fishes and frogs.

(ii) Warm-blooded (homoiothermous) animals, i.e., they are able to maintain a constant body temperature like birds and mammals.

(iii) Dry and cornified skin, epidermal scales or scute like crocodile and lizard covers body of reptiles.

(iv) If sexes are separate i.e., males and females are distinct like in ascaris or nereis, then they are dioecious.

Frog is a cold blooded amphibian, i.e. its body temperature varies with the temperature of the environment.

Parrot is a warm blooded animal, i.e. its body temperature remains constant irrespective of the temperature of the environment.
Lizard are reptiles and possesses dry and cornified skin. Earthworm belongs to Annelida and is a hermaphrodite animal, i.e., both male and female sex organs are present in the single individual. The correct answer is option A - '(i) Frog, (ii) Parrot (iii) lizard, (iv) Earthworm'.
