Problem statement: Answer the multiple choice question.
Question: Which compound has a 6.058\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccccc1-c1c(C)nn2c(N3CCN(c4ccccc4OC)CC3)cc(C)nc12
b: COc1ccc2nc(/N=C/c3c(C)[nH]n(-c4ccc(C)cc4)c3=O)sc2c1
c: CN(Cc1nc(-c2ccncc2)no1)S(=O)(=O)c1ccc(Cl)cc1
d: CCN(C(=O)Cn1cnc2cc([N+](=O)[O-])ccc2c1=O)C1CCS(=O)(=O)C1
Answer: d. CCN(C(=O)Cn1cnc2cc([N+](=O)[O-])ccc2c1=O)C1CCS(=O)(=O)C1
