…………… is compulsory for advertisements.

(A) Expenditure

(B) Effort

(C) Both of the above

(D) Television

Answer -The source selects expenditure because payment distinguishes advertising from unpaid publicity. In practice an identified sponsor makes advertising efforts as well as paying for them, so option (C) is also defensible under the broad wording. The question does not state that it asks only for the distinguishing feature.

(A) Expenditure is the defining requirement: advertising is paid communication. Effort is practically involved too; the question is asking for the distinguishing characteristic.
