Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): Increase in Carbon dioxide would melt polar ice.
Reason (R): Global temperature would rise.

In the light of the above statements, choose the most appropriate answer from the options given below:

Both (A) and (R) are correct and (R) is the correct explanation of (A)

The assertion (A) says that an increase in Carbon dioxide would melt polar ice.

The reason (R) explains why this happens. When global temperature rises due to increased CO2 levels, it causes the polar ice to melt.

In other words, the reason (R) provides a logical explanation for the assertion (A). The increased global temperature is the mechanism by which the increased CO2 levels cause the polar ice to melt.

Without the increased global temperature, the increased CO2 levels would not cause the polar ice to melt.

Thus, both statements are true, and the reason (R) is the correct explanation for why the assertion (A) is true.
