A firm is operating in a market where it can sell more only by lowering the price of the good. Arrange the changes in total revenue of this firm in a sequential order.

(A) Total revenue falls.

(B) Total revenue starts from origin.

(C) Total revenue increases at a diminishing rate.

(D) Total revenue reaches its maximum.

Choose the correct answer from the options given below:

Option 1: (B), (C), (D), (A) -> When a firm operates in imperfect competition (downward-sloping demand curve), the total revenue follows a predictable sequence: It starts from the origin when quantity is zero (B), then increases at a diminishing rate as price falls and quantity rises (C), reaches maximum when marginal revenue equals zero (D), and finally falls when further price reductions make marginal revenue negative (A). This represents the typical inverted U-shaped total revenue curve for a monopolistic firm. -> correct
