Correct Answer:
B. 3
This question requires specific knowledge of the composition of a statutory body, the Price Control Council. The correct answer is '3'. The number of ministers appointed to a council is a precise detail stipulated within the Act itself, reflecting the legislative intent regarding the council's structure and representation. Such details are critical for understanding the governance and operational framework of the body. Options A, C, and D are incorrect because they do not align with the specific number of ministers prescribed by the Act for the Price Control Council. Accurate recall of these numerical details is essential for legal and administrative compliance.
