Solution

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 20C) while the latter includes organisms which can thrive only in lower temperatures (below 20C). Corals, some insects and a majority of the reptiles are thermophiles. Arctic crustaceans are examples of cryophiles.
