TANGEDCO (Tamil Nadu Generation and Distribution Corporation) is the primary:

Electricity utility in the state
Coal mining company
Renewable energy developer
Water resources management agency

The correct answer is: a) Electricity utility in the state.

TANGEDCO is the Tamil Nadu Generation and Distribution Corporation. It is a state-owned electricity utility company in India. It is responsible for the generation, transmission, and distribution of electricity in the state of Tamil Nadu.

The other options are incorrect because:

  • b) Coal mining company: TANGEDCO does not mine coal. It purchases coal from other companies to generate electricity.
  • c) Renewable energy developer: TANGEDCO does develop renewable energy projects, but it is not its primary focus. Its primary focus is on the generation, transmission, and distribution of electricity.
  • d) Water resources management agency: TANGEDCO is not responsible for water resources management. This is the responsibility of the Tamil Nadu Water Resources Department.
