The primary agency responsible for disaster management in Punjab is the:

The correct answer is: a) State Disaster Management Authority (SDMA).

The SDMA is a state-level body responsible for disaster management in Punjab. It was established in 2005 under the Disaster Management Act, 2005. The SDMA is headed by the Chief Secretary of Punjab and has representatives from various government departments, including the police, the civil defence, the health department, and the revenue department.

The SDMA is responsible for planning, coordinating, and implementing disaster management activities in Punjab. It also provides training to government officials and the public on disaster preparedness and response.

The other options are incorrect because:

• The National Disaster Response Force (NDRF) is a central government agency responsible for disaster response. It is not responsible for disaster management in Punjab.
• The India Meteorological Department (IMD) is a central government agency responsible for weather forecasting and warning. It is not responsible for disaster management in Punjab.
• The Central Water Commission (CWC) is a central government agency responsible for water resources management. It is not responsible for disaster management in Punjab.
