How is telemarketing defined?

• A. The practice of using interactive telephone communications for the purpose of promoting, directly or indirectly, the supply or use of a product or of the purpose of promoting, directly or indirectly, any business interest
• B. A radio advertisement
• C. A direct mail campaign
• D. Door-to-door sales

Answer: (A)

Telemarketing is defined by using interactive telephone communications to promote, directly or indirectly, the supply or use of a product or the promotion of any business interest. The key point is the two-way, active phone contact aimed at persuading or informing a potential customer about products, services, or business interests.

This fits best because it specifies the method (telephone) and the purpose (promotion), including both direct selling and indirect promotion. It’s distinct from a radio advertisement (a broadcast), direct mail (a mail-based approach), or door-to-door sales (in-person).
