Answer:
Option B is the correct answer.
Step-by-step explanation:
Option B is correct because when a firm produces or manufactures the product then various types of costs are associated with that product like variable costs, fixed costs, etc. Profit is the main motive of every firm so the manager decides the price of the commodity in such a way that it can compete in the market and generate revenue for the firm. Therefore, it is the responsibility of the manager to look after the pricing strategy at which the product has to sell.
