Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.837% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COc1ccc(C2CC(=O)c3cnn(-c4nc(C)cc(C)n4)c3C2)cc1OC
(b) Oc1ccc2ccccc2c1C=Nc1ccccc1Br
(c) C=CCNC(=O)c1onc(CCl)c1C(=O)OC
(d) O=C(Nc1ccc2c(c1)OCO2)c1ccc(Br)c(S(=O)(=O)N2CCCC2)c1
(e) COc1ccc(OCC(=O)N/N=C(\C)CC(=O)Nc2cccc([N+](=O)[O-])c2)cc1
Answer: a. COc1ccc(C2CC(=O)c3cnn(-c4nc(C)cc(C)n4)c3C2)cc1OC
