Task: Answer the multiple-choice question.
Question: Which compound exhibits a -2.295\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(CCNC(=O)c2ccc(S(=O)(=O)N(C)c3ccccc3)cc2)cc1OC
(b) CC(=O)Nc1c(I)c(NC(C)=O)c(I)c(C(=O)O)c1I.CNC[C@H](O)[C@@H](O)[C@H](O)[C@H](O)CO
(c) O=C(C1CCCCC1)N1CCN(C(=O)C2CCCCC2)CC1
Answer: c. O=C(C1CCCCC1)N1CCN(C(=O)C2CCCCC2)CC1
