Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.786\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cccc(OC)c1CN1CCCC(C(=O)c2cccc(Cl)c2)C1
(b) Cc1cc(C)n(-c2ccc(S(N)(=O)=O)cc2[N+](=O)[O-])n1
(c) CCOC(=O)c1c(C)oc2cc(Cl)c(O)c(CN(C)C)c12
(d) CN(C(=O)CCN1C(=O)c2ccccc2C1=O)c1ccccc1
Answer: c. CCOC(=O)c1c(C)oc2cc(Cl)c(O)c(CN(C)C)c12
