Question 32: Though disposing of nuclear waste remains a concern, nuclear plants are often subsidized because of the steady, carbon-free power provided.
Consider the verb 'provided' in the given sentence. It is not clear which noun this verb relates to. What is being provided? Steady, carbon-free power. So, this is the object of the verb. The entity that provides—the subject—is 'nuclear plants'. However, this entity is not referred to in the subordinating clause. To correct this error, either the subject or a pronoun referring to it has to be put in the clause. The correct option, is therefore one which says ‘the steady, carbon-free power they provide'.
Note that ‘dispose of’ the correct usage of the phrasal verb. To 'dispose of' something is to get rid of it. The usage 'dispose off’, fairly common in India, is incorrect.
The question is " Choose the grammatically correct option "
Choice B is the correct answer.
