I am having trouble figuring out if any of the following sentences is grammatically correct:
(A) People perceive him as manipulative, and therefore do not trust him.
(B) People perceive him as manipulative, and therefore not trusting him.
(C) People perceive him as manipulative, therefore not trusting him.
I understand the "and" is a conjunction and generally connects two independent clauses, but what about "and therefore"? If "and therefore" functions as a conjunction, then (A) would be incorrect because "do not trust him" is not an independent clause. Is this correct?
(B) and (C) also look suspicious to me, but I can't explain why.
