Consider the two statements given below: Statement-1: Infrared waves are also called heat waves. Statement-2: Water molecules readily absorb infrared waves. Select the correct answer using the code given below:

Infrared waves are called heat waves because they are strongly absorbed by most substances (especially water and many organic molecules), causing them to heat up by setting molecules into vibration. Statement-1 is therefore true. Water molecules do readily absorb infrared radiation due to vibrational transitions of O–H bonds, so Statement-2 is also true. However, infrared waves are called heat waves primarily because of their thermal effect on matter in general (their absorption produces a sensation of heat), not specifically because water absorbs them. Thus Statement-2 is not the correct explanation of Statement-1.
