Eileen Developed an Extremely Successful Advertising and Promotion Campaign for a Client

Eileen developed an extremely successful advertising and promotion campaign for a client in the United States. The client wanted to roll out the same campaign to markets worldwide, but Eileen cautioned against doing this, most likely because

A) differences in languages, customs, and culture might make the campaign meaningless and ineffective in some markets.
B) copyright and intellectual property concerns prevented her from wanting to share her good ideas outside of the U.S. market.
C) she had not applied for or received international certification that was required for working outside the United States.
D) she was unfamiliar with the code of ethics for advertising in other countries.
E) she did not have the budget for a global rollout.
