When Florists Make Floral Arrangements the Flowers Are Stuck into a Piece

When florists make floral arrangements the flowers are stuck into a piece of foam that is soaked in water and cut to fit the flowers being arranged. An ad placed in Floral Management for Aquafoam, one of the principal brands of foam used by florists, describes a contest with a $10,000 prize that any florist can enter by simply placing a telephone order for Aquafoam. The objective of this ad is to:

A) eliminate Aquafoam's competition.
B) counteract product cannibalization.
C) improve the company's relations with its dealers.
D) support Aquafoam's personal selling efforts.
E) do all of the above.
