Assertion: The focus of selling concept is to sell the existing product through aggressive selling and promotional efforts.
Reasoning: Selling concept assumes that customers can be persuaded and manipulated to buy the product.

Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

It was assumed that the customers would not buy, or not buy enough, unless they are adequately convinced and motivated to do so. Therefore, firms must undertake aggressive selling and promotional efforts to make customers buy their products. The use of promotional techniques such as advertising, personal selling and sales promotion were considered essential for selling of products. Thus, the focus of business firms shifted to pushing the sale of products through aggressive selling techniques with a view to persuade, lure or coax the buyers to buy the products. Making sale through any means became important. It was assumed that buyers can be manipulated but what was forgotten was that in the long run what matters most is the customer satisfaction, rather than anything else.
