Question

Which alternative energy source has the least long-term impact on the environment?
I. Solar power
II. Wind power
III. Nuclear power

• A. I only
• B. II only
• C. III only
• D. I and II only
• E. II and III only

Answer 1

The correct option is D I and II only

I. Solar power is the energy generated from solar light i.e. the sunlight.

II. Wind power is the energy generated by the wind.

III. Nuclear power is the energy generated through nuclear reactions.

Since solar light and wind has no danger and has least impact, so solar power and wind power have the least long-term impact on the environment.

So, the correct answer is 'I and II only'
