Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.146\% 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] COc1ccc(C(=O)N2CCN(S(=O)(=O)N3CCOCC3)CC2)cc1OC
[b] Cl.O=C(Nc1nc2n(n1)C(c1ccccc1)C=C(c1ccccc1)N2)c1ccco1
[c] O=C(c1cc2cc(C(F)(F)F)ccc2s1)N1CCOCC1
Answer: a. COc1ccc(C(=O)N2CCN(S(=O)(=O)N3CCOCC3)CC2)cc1OC
