The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the permissible ambient noise levels for a silent zone during daytime as specified by the Central Pollution Control Board (CPCB). 2. **Identifying the Source**: The Central Pollution Control Board (CPCB) is the regulatory authority that sets standards for noise pollution in India. 3. **Defining Silent Zones**: Silent zones are areas where noise levels are expected to be lower than in regular urban environments, typically near hospitals, schools, and residential areas. 4. **Referencing Noise Levels**: According to the CPCB, permissible noise levels are categorized based on different zones. For silent zones, the permissible noise level during the daytime is generally lower than in other zones. 5. **Citing the Permissible Level**: The permissible ambient noise level for silent zones during daytime is set at 50 decibels (dB). 6. **Conclusion**: Therefore, the answer to the question is that the permissible ambient noise level for a silent zone during daytime is **50 dB**. ---
