Task: Answer the multiple choice question.
Query: Which drug has a 8.218\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1c2ccoc2cc2oc(C)cc(=O)c12
(b) O=c1ncn(-c2ccccc2F)c2ncccc12
(c) O=C(c1cccc(F)c1)N1CCN(c2cccc(Cl)c2)CC1
(d) O=C1ON=C(c2ccc(Cl)cc2)/C1=C/c1ccc(O)cc1
(e) CC(CN1CCOCC1)OC(=O)COc1ccc(F)cc1
Answer: a. COc1c2ccoc2cc2oc(C)cc(=O)c12
