Correct Answer:
B. Punjab Prevention of Hoarding Act 2020
The correct answer is Punjab Prevention of Hoarding Act 2020. This specific legislation was enacted in Punjab in 2020 with the explicit purpose of combating hoarding practices within the province. It provides the legal framework to prevent the artificial creation of shortages and to ensure the availability of essential commodities. Options A, C, and D are incorrect because they refer to different types of legislation or general acts that do not specifically address hoarding in Punjab in 2020, or they are entirely different legal frameworks.
