• CPCB Regulatory Norms (2015): Under the Environment (Protection) Rules and Central Pollution Control Board guidelines for thermal power plants, condenser cooling water discharge must not exceed 10°C above the ambient temperature of the intake water body ($\Delta T \le 10^\circ\text{C}$).
• Ecological Protection: Limiting thermal discharge protects aquatic flora and fauna from acute thermal shock, elevated metabolic strain, and depleted dissolved oxygen (DO) levels in receiving rivers, lakes, or estuaries.

Correct option: (1) 10°C
