Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 30.145\% 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 other words.
Options:
a: CCC(C(=O)Nc1nnc(-c2ccco2)s1)c1ccccc1
b: CC(C)CC(=O)Nc1ccc(-c2cn3cccnc3n2)cc1
c: O=C(O)CCCCCN1C(=O)C(O)=C(C(=O)/C=C/c2ccccc2)C1c1ccc2c(c1)OCO2
d: COc1ccc(C2NC3=C(CCC3)C3(C#N)C(OC)(OC)N=C(N)C23C#N)cc1
e: CCOC(=O)c1ccc2nc(C)c(CCC(C)=O)c(Cl)c2c1
Answer: b. CC(C)CC(=O)Nc1ccc(-c2cn3cccnc3n2)cc1
