Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.503\% 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=C(COc1ccc2c(c1)OCO2)Nc1nnc(Cc2ccccc2)s1
(b) COC(=O)N1CCc2c(sc(NC(=O)C3=COCCO3)c2C#N)C1
(c) CC(C)(C)c1ccccc1NC(=O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
(d) Cl.OCc1cc(CO)c(O)c(CCc2ccccc2)n1
(e) O=C(CCC(=O)N1CCCC1)Nc1ccc(Cl)c(Cl)c1
Answer: b. COC(=O)N1CCc2c(sc(NC(=O)C3=COCCO3)c2C#N)C1
