Assertion (A): The temperature at the poles is frigid.
Reason (R): The rays of the sun are direct at the poles.

Choose the correct option:
i. Both A and R are true and R is the correct explanation of A.
ii. Both A and R are true but R is not the correct explanation of A.
iii. A is true but R is false.
iv. A is false but R is true.

The assertion that the temperature at the poles is frigid is true, while the reason that the rays of the sun are direct at the poles is false. As a consequence, the chosen option is iii. A is true but R is false.

To understand the assertion and reason in the question, we need to examine each statement:

Assertion (A): The temperature at the poles is frigid.

This statement is true. The polar regions, both the Arctic and the Antarctic, are characterized by extremely cold temperatures. This is largely due to their location at the extreme ends of the Earth, where sunlight is limited.


Reason (R): The rays of the sun are direct at the poles.

This statement is false. In reality, the rays of the sun are not direct at the poles. Instead, they strike at a very oblique angle. This indirect angle is one of the main reasons why these regions remain so cold. Direct sunlight, like what is experienced at the equator, delivers more energy and heat.



Therefore, when we analyze these statements, the correct answer is:
iii. A is true but R is false.
The poles are frigid because the sun's rays are indirect, leading to less energy and warmth being received in these areas.
