Q.A 'selling point' refers to:

A selling point is a characteristic of the product, not of the customer or the shop — that distinction decides the answer.

Option (a) describes a buying motive, (c) describes a point of sale, and (d) is a salesman's earning — none is a selling point.

A selling point is any feature, quality, or characteristic of the product itself — such as its durability, price, design, safety, or after-sale service — that a salesman uses to attract a customer and persuade him to buy. It belongs to the product and answers the buyer's question 'why should I buy this?'.

Examining the options:

• (a) describes a buying motive — the inner urge inside the customer's mind — which is the opposite side of a sale, not a selling point.
• (b) correctly states that a selling point is a feature/quality of the product used to persuade the buyer.
• (c) describes a point of sale or display counter, not a selling point.
• (d) refers to a salesman's commission or earning, which is unrelated.
