Correct Answer:
B. Punjab Prevention of Hoarding Act 2020
The question asks for the official citation of the Act. Legal acts are formally identified by their precise title and the year they were enacted. Punjab Prevention of Hoarding Act 2020 is the exact and correct legal title as per the legislative document itself. Options like "Punjab Anti-Stockpiling Act 2020," "Punjab Anti-Black Marketing Act 2020," and "Punjab Trade Regulation Act 2020" are incorrect because they use different terminology or are broader in scope, not reflecting the specific, official name of the legislation. The correct citation is crucial for legal accuracy and reference.
