The use of telephone systems (audio and text messaging) to sell products directly to potential customers, also known as telemarketing.

• A. Direct marketing
• B. Telemarketing
• C. Telesales
• D. Marketing research

Answer: (C)

The main idea is selling by phone. When a business uses telephone systems to reach potential customers with the aim of closing a sale, that activity is called telesales. It zeroes in on converting interest into a purchase directly over the phone, often using scripts and closing techniques. Telemarketing is a broader label that can include both selling and other phone-based marketing activities like generating leads or collecting information, so it isn’t as precise for the act of selling itself. Direct marketing covers any direct-channel approach to prompt a response, not limited to phone sales, and marketing research is about gathering market data, not making sales. So the best fit for selling directly to customers over the phone is telesales.
