Correct Answer:
B. Imprisonment or fine
The Act imposes strict measures to ensure compliance and transparency in the supply chain of essential goods. Failure to report inventory is a serious offense that can hinder monitoring and lead to market distortions. Consequently, the penalty for not reporting inventory is severe, typically involving Imprisonment or fine (B). 'No penalty' (A) or 'Only warning' (C) would undermine the Act's effectiveness. A 'Life ban' (D) is generally too extreme for this specific offense, though other severe penalties might exist for repeated or very serious violations.
