Task: Answer the multiple-choice question.
Query: Which compound has a 4.549\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(c1ccc(=O)[nH]c1)N1CCN(S(=O)(=O)c2cc(C(F)(F)F)ccc2Cl)CC1
(b) Cc1ccc(S(=O)(=O)N2CCN(C(=O)COC(=O)c3ccc(Cl)nc3)CC2)c(C)c1
(c) COc1cccc(NC(=O)c2cccnn2)c1
Answer: a. O=C(c1ccc(=O)[nH]c1)N1CCN(S(=O)(=O)c2cc(C(F)(F)F)ccc2Cl)CC1
