Task: Answer the multiple-choice question.
Question: Which compound has a -10.409% 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 other words.
Options:
a.) O=C1COc2ccc(C(=O)COC(=O)COc3ccccc3[N+](=O)[O-])cc2N1
b.) O=C(O)c1ccc(-n2c(/C=C/c3cccc([N+](=O)[O-])c3)nc3ccccc3c2=O)cc1
c.) CC(C)CN(C(=O)CN(C)C(=O)c1ccco1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
d.) CC1CCCN(C2(O)C(=O)Nc3ccc([N+](=O)[O-])cc32)C1
e.) N=C1C(c2ccccc2)=C(O)CN1c1cccc(S(N)(=O)=O)c1
Answer: a. O=C1COc2ccc(C(=O)COC(=O)COc3ccccc3[N+](=O)[O-])cc2N1
