Solution

The correct option is A Both statements are correct, and statement 2 is the correct explanation for statement 1.
Dynamo is a device used in all power plants. A dynamo converts mechanical energy to electrical energy. When the coil of dynamo is rotated in a magnetic field, electrical energy is generated.

Since the power plants are built to deliver electrical energy, a dynamo (or a generator) is essential for all power plants.

Hence, both statements are correct. Statement 2 explains statement 1.
