Problem statement: Answer the multiple-choice question.
Query: Which compound has a 6.771\% 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 other words.
Options:
(a) O=C(CSc1nnc(COc2ccccc2)n1-c1ccccc1)c1cccs1
(b) CCOCCCNC(=O)/C(C#N)=C/c1ccc([N+](=O)[O-])o1
(c) Cn1cc(CNCc2ccccc2OCC(O)CN2CCc3ccccc3C2)cn1
(d) CCOC(=O)N1CCN(C(=O)Cn2ncc3c2-c2ccccc2OC3)CC1
Answer: b. CCOCCCNC(=O)/C(C#N)=C/c1ccc([N+](=O)[O-])o1
