Task: Answer the multiple choice question.
Query: Which compound has a 0.542\% 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) COC(=O)CN(c1ccc(OC)cc1)S(=O)(=O)c1ccc(OC)c(OC)c1
(b) O=C(NCC1CCCO1)C1CCN(C2CCN(C(=O)C3CCCCC3)CC2)CC1
(c) O=C(Cn1nc(-c2ccco2)ccc1=O)Nc1ccc(Br)cc1
Answer: a. COC(=O)CN(c1ccc(OC)cc1)S(=O)(=O)c1ccc(OC)c(OC)c1
