Correct option is C
The error is in (C) engaged in pursuits of philanthropy.
Explanation:
The verb “encouraged” should be followed by the base form of a verb (infinitive) with to, not the past participle.
· Correct form: “to engage in pursuits of philanthropy”
Corrected Sentence:
The priest encouraged the members of his church to engage in pursuits of philanthropy so that no man would be in need.
Analysis of other parts of the sentence:
(A) The priest encouraged
· Analysis: Grammatically correct. Encouraged is properly used as the main verb.
(B) the members of his church to
· Analysis: Correct. The structure encourage + someone + to is standard.
(D) so that no man would be in need
· Analysis: Correct. This is a proper purpose clause using so that + modal verb.
