Read the statements A and B carefully -

Statement A : During the cold season lizards go into a long and deep sleep.

Statement B : Some animals go into a long, deep sleep in certain seasons.

Choose the correct answer from the following :

The correct answer is Both ‘A’ and ‘B’ are correct and ‘B’ explains ‘A’.

Step-by-step Explanation:

1. Analysis of Statement A: "During the cold season lizards go into a long and deep sleep."
Lizards are cold-blooded animals (ectotherms) that cannot regulate their body temperature internally. During winter, when temperatures drop, their body activities slow down significantly, and they go into a long, deep sleep known as hibernation (or brumation). Therefore, Statement A is correct.

2. Analysis of Statement B: "Some animals go into a long, deep sleep in certain seasons."
Many animals undergo long, deep sleeps during extreme weather conditions to survive—for example, bears, frogs, and lizards hibernate during cold winters, while some other animals undergo aestivation during hot summers. Therefore, Statement B is a correct general scientific fact.

3. Relationship between Statement A and Statement B:
Statement A presents a specific instance of seasonal long sleep (lizards in cold season), while Statement B provides the underlying biological concept (that certain animals go into long, deep sleep during specific seasons). Thus, Statement B provides the general explanation/reason for the phenomenon observed in Statement A.

Hence, both statements are correct, and Statement B explains Statement A.
