    E No correction required Correct Answer Incorrect Answer

    Solution

    (a) According to the rule, 'one of the' is followed by a plural noun and a singular form of a verb, so the use of options (b) and (d) is incorrect. Option (c) does not give a meaningful sentence moreover, the use of 'were' is incorrect. So, option (a) is contextually and grammatically correct as it discusses the concern related to the contact ratio of the gear pair i.e., to work on optimisation. Hence, option (a) is correct.
