D Correct answer
Explanation

The question is about pronoun agreement. Options (1), (2) and (3) are ruled out since the pronoun 'they' could ambiguously refer to ‘fuel cells’ or to 'A majority of the respondents'. Option (5) eliminates the ambiguity by referring to modifying noun itself but ends up introducing a new error by eliminating the connector 'that'. Option (4) is clear and grammatically correct. Hence (4).
