Answer #1

Answer -

Correct option is B.

The solar power is energy produced from direct sunlight. It is going to replace many coal-based power plant in near future.

Parabolic trough - It is a parabolic mirror shaped device which converges the incoming solar radiation to store energy. It is an alternative to the solar power plant.

Dish/Engine - It consists of a disc-shaped solar plate which reflects the incoming solar radiation to one point, which generates energy and stores energy.

Hence all three uses an alternate source of energy instead of fossil fuels.
