Task: Answer the multiple choice question.
Query: Which drug exhibits a -15.694\% 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) CC1(C(=O)N2CC3(CC(c4cccc(NC(=O)CC(c5ccccc5)c5ccccc5)c4)=NO3)C[C@@H]2C(N)=O)CC1
(b) O=C(c1ccco1)N1CCN(c2ccc([N+](=O)[O-])cc2F)CC1
(c) COC(=O)c1ccc(CSc2nc(N3CCOCC3)c3c(c2C#N)CC(C)(C)OC3)o1
(d) CCOc1cc(C(=O)NCc2ccco2)cc(OCC)c1OCC
(e) C=CCNC(=O)C1CC(=O)N(c2ccc(OCC(=O)Nc3ccc(C)cc3)cc2)C1
Answer: b. O=C(c1ccco1)N1CCN(c2ccc([N+](=O)[O-])cc2F)CC1
