Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.168\% 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(Nc1nnc(-c2ccccc2SCc2ccccc2F)s1)Nc1ccccc1F
[b] O=C(OCc1csc(-c2ccccc2)n1)c1ccccc1O
[c] CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)CN1C(=O)N(C)C2(CCCCC2)C1=O
Answer: a. O=C(Nc1nnc(-c2ccccc2SCc2ccccc2F)s1)Nc1ccccc1F
