Question

Regarding the assertion and reason, choose the correct option:
Assertion [A]: Most reptiles are examples of thermophiles.
Reason [R]: Thermophiles can thrive only in low temperatures.

• A. Both A and R are correct and R explains A
• B. Both A and R are correct but R does not explain A
• C. A is correct but R is incorrect
• D. Both A and R are incorrect

Answer 1

The correct option is C A is correct but R is incorrect

Stenothermal organisms are those which can thrive only within a limited temperature range. They could be further categorised into two groups- thermophiles and cryophiles. The former refers to those organisms which can thrive only in high temperatures (at least above ${20}^{\circ }C$) while the latter includes organisms which can thrive only in lower temperatures (below ${20}^{\circ }C$). Corals, some insects and a majority of the reptiles are thermophiles. Arctic crustaceans are examples of cryophiles.
