Given below are two statements, an Assertion (A) and a Reason (R). Choose the correct answer from the options given below:

Both the assertion and the reason are true, and the reason correctly explains the assertion.

The assertion is sound because Marshall McLuhan did classify radio, cinema and photographs as hot media in his theory.

The reason is also true, since hot media are defined as high-definition, information-rich forms that ask little from the audience to complete the message.

This low participation is exactly why those high-definition forms are grouped as hot rather than cool.

Cool media like the telephone or cartoon give less data and demand more filling-in by the receiver.

So the reason supplies the very criterion behind the assertion's classification.
