Every Open House we held since 2013 reaffirmed our belief that there is a need for human intervention to "retain its trust and credibility over age of" anonymous communication.
(I) to retain trust and credibility in this age of
(II) to retaining trust and credibility ageing
(III) for retention of trust and credible age of

Options

A. Only (I) is correct
B. Only (III) is correct
C. Both (I) and (II) are correct
D. Both (II) and (III) are correct

Answer

A

Explanation

"to retain trust and credibility in this age of" is the correct phrase to make the sentence grammatically correct. If we go by the options considering their grammer syntax, only option (I) fits into the sentence perfectly adding the required meaning to the sentence. Moreover, "in this age of anonymous communication" is the correct phrase usage which means "in this distinct period of anonymous communication". Hence (a) is the correct option.
