Select the correct option based on statements below:
 Assertion (A): As a gas bubble rises from the bottom of a lake, its volume decreases. Reason (R): As the gas bubble rises from the bottom of a lake-the pressure of the gas within decreases.
 1 (A) is True but (R) is False. 2 (A) is False but (R) is True. 3 Both (A) and (R) are True and (R) is the correct explanation of (A). 4 Both (A) and (R) are True but (R) is not the correct explanation of (A).

Given below are two statements:
 Assertion (A): A gas can be liquified at any temperature by an increase of pressure alone. Reason (R): On increasing pressure, the temperature of gas decreases.

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.
