Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.178\% 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) O=C1CC(NNC(=O)c2ccc(Br)cc2)C(=O)N1
(b) CCOc1cccc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2ccncc2)c1
(c) CCN(CC(=O)NCc1ccc(F)cc1)Cc1nc2cc(Cl)ccc2c(=O)[nH]1
(d) COC(=O)CCCC(=O)N1CCCC(CNS(=O)(=O)c2ccc(OC)cc2)C1
(e) C/C(CC1CC(COCC(C)C)OC1=O)=N\NC(N)=S
Answer: a. O=C1CC(NNC(=O)c2ccc(Br)cc2)C(=O)N1
