Explanation for Incorrect Answer A :

Choice (A) involves awkward phrasing. It would be more appropriate to say “its toll in human misery is greater.”

Explanation for Incorrect Answer B :

Choice (B) involves unclear pronoun reference. It is not clear whether the pronoun “it” refers to “surface mining” or “deep mining.”

Explanation for Incorrect Answer C :

Choice (C) involves unclear pronoun reference. It is not clear to what the pronoun “it” is meant to refer.
