Correct Answer:
B. 7 days
The correct answer is 7 days. When a whistle-blower receives a show-cause notice for a false disclosure, they are typically granted 7 days to submit a written reply. This timeframe is a standard procedural requirement, ensuring that the individual has adequate opportunity to present their defense or explanation, thereby upholding principles of natural justice and due process. Options such as 3 days, 15 days, or 30 days are incorrect because they do not align with the specific stipulated period provided in the relevant regulations for responding to such a notice concerning false disclosures.
