OFFICIAL EXPLANATION
While some economists propose that agricultural land be used to help solve the energy crisis by converting arable land from foods to bio-fuel, a majority of analysts believe that bio-fuels should be produced only from non-food crops, whose use will impact the environment less.
(A) whose use will impact the environment less
This answer choice makes correct and unambiguous use of the possessive relative pronoun whose to refer to the use of non-food crops:
- non-food crops' use == use of non-food crops --> non-food crops whose use
This answer choice also concisely expresses the meaning of the sentence by using the verb impact and the adverb less.
(B) the use of which will have a lesser impact on the environment
Incorrect.
This answer choice is stylistically flawed. The phrase the use of which will have a lesser impact is wordy. Look for an answer choice that is more concise.
(C) having less of an impact on the environment if used
Incorrect.
This answer choice is stylistically flawed.
It unnecessarily makes use of the conditional (if used) within the modifying clause having less of an impact. This construction also creates ambiguity, as it is not clear what if used refers to - the environment or non-food crops.
Similarly, the use of the participle clause having less of an impact is ambiguous as it could refer to analysts, bio-fuels, or non-food crops.
Normally a Ving modifying phrase provides a result of the previous clause or gives further information about the previous clause (the subject and verb); however, that is not the case here, as the having would not logically make sense if it referred to a majority of analysts believe.
(D) lessening the impact of its use on the environment
Incorrect.
This answer choice is grammatically incorrect. The pronoun its does not agree with the plural noun it is meant to refer to - non-food crops.
(E) with lower environmental impacts of using them
Incorrect.
This answer choice is stylistically flawed. The use of the pronoun them is ambiguous, as it could refer to bio-fuels, or non-food crops.
In addition, the use of the preposition with is also awkward and confusing, as it is not clear what with refers to.

(A) whose use will impact the environment less
The possessive relative pronoun whose correctly refer to the 'non-food crops', reducing the ambiguity and wordiness.
Hence the correct choice is A.
(B) the use of which will have a lesser impact on the environment
The phrase the use of which will have a lesser impact is wordy and awkward. Eliminate.
(C) having less of an impact on the environment if used
The clause, 'having less of an impact', is confusing. What is it referring to? Is it analysts, or bio-fuels, or non-food crops? Having does not make sense if it referring to a majority of analysts believe. Condition, 'if used', is unnecessary.
(D) lessening the impact of its use on the environment
Pronoun error, 'Its' does not agree with the plural noun, "non-food crops". Eliminate
(E) with lower environmental impacts of using them
Preposition 'With' is confusing. What is it referring to?
Pronoun error with 'Them'. what is it referring to? Is it referring to bio-fuels, or non-food crops?
Eliminate
