Assertion (A): Most television channels depend upon national advertising for their survival. Reason (R): It is cheaper to advertise on television as it reaches specific audiences. Codes: (A) Both (A) and (R) are true. (B) Both (A) and (R) are true, but (R) is not the correct explanation of (A). (C) (A) is true, but (R) is false. (D) (A) is false, but (R) is true. Correct Ans: (C) Explanation: Most television channels rely on national advertising for financial sustainability. Broadcasters generate revenue mainly through advertisements from large brands and corporations, which pay for airtime to reach a broad audience. Advertising allows TV networks to offer free or low-cost programming while maintaining operations. Therefore, Assertion (A) is true. However, the Reason (R) is false because television advertising is not necessarily cheaper. In fact, TV commercials require high production costs and expensive airtime slots, especially on popular channels. Although television provides broad exposure and audience targeting through specific time slots and programs, it remains one of the costliest advertising mediums compared to digital or print media. Since Assertion (A) is correct, but Reason (R) is incorrect, the right answer is (C): (A) is true, but (R) is false. In conclusion, national advertising serves as a primary revenue source for television channels, but it is not cheaper than other advertising forms. Businesses choose television ads for wide audience reach and credibility, despite their high costs.
