Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.892% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOC(=O)/C(C#N)=C/C1=C(N2CCCC2)CC(C)(C)OC1
b: CCOC(=O)C(C)n1cnc2c1c(=O)[nH]c(=O)n2C
c: Nc1nonc1-c1nc2ccccc2n1CC(=O)Nc1ccccc1
d: COc1ccc(OCCCc2c(C)n[nH]c2C)cc1
e: CN(C)c1[nH]c(=O)c(C#N)c2c1CCN2Cc1ccccc1
Answer: b. CCOC(=O)C(C)n1cnc2c1c(=O)[nH]c(=O)n2C
