A single advertisement for a number of brands or services is called: 

(A) umbrella

(B) universe

(C) bouquet

(D) collage

Correct Ans: (A)

Explanation:
Advertisers refer to a single advertisement promoting multiple brands or services as an umbrella advertisement. They use this approach to group related products or services under a unified message, saving costs and presenting a cohesive brand image.

The other options do not represent this concept. A universe refers to the total audience or population in research. A bouquet is often used for grouping TV channels or unrelated items. A collage refers to a collection of images or visuals, not an advertising format.

By creating umbrella advertisements, advertisers effectively showcase multiple offerings within a single campaign.
