Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.641\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(Nc1ccc(Cc2ccncc2)cc1)c1ccco1
(b) CCOC(=O)C1(CCOC)CCN(Cc2ccccc2-c2ccco2)CC1
(c) COC(=O)C1=C(c2ccc(Cl)c(C(F)(F)F)c2)C[C@@H]2CC[C@H]1N2C(=O)NCc1ccco1
Answer: a. O=C(Nc1ccc(Cc2ccncc2)cc1)c1ccco1
