Task: Answer the multiple-choice question.
Question: Which drug exhibits a 20.793\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccc(C(=O)Nc2ccc(N3CCN(C(=O)C(C)C)CC3)cc2)cc1[N+](=O)[O-]
b: CC1CN(C(=O)c2ccccc2NS(=O)(=O)c2cccc([N+](=O)[O-])c2)CC(C)O1
c: Clc1cccc(CN2CCCCC2c2cccnc2)c1
d: N/C(Cc1ccc([N+](=O)[O-])cc1)=N\OC(=O)c1ccco1
e: CC(C)Oc1cccc(C2NC(=O)c3ccccc3O2)c1
Answer: b. CC1CN(C(=O)c2ccccc2NS(=O)(=O)c2cccc([N+](=O)[O-])c2)CC(C)O1
