Correct Answer:
C. Maximum price fixed under the Act
Section 7 is a core enforcement provision for price control. The correct option, C) Maximum price fixed under the Act, is accurate because this section directly prohibits selling essential commodities above the legally established ceiling. This is the primary mechanism to prevent profiteering and ensure affordability, making the fixed maximum price the definitive legal limit. Distractor A, Market price, is incorrect because market prices can exceed the controlled price, which the Act aims to prevent. Distractor B, Retailer's price, and Distractor D, Wholesale rate, are specific types of prices, but the overarching prohibition is against exceeding the *maximum* price set by the Act.
