Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -7.946\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1cccc(CCN2CCC(CNS(=O)(=O)c3cc(-c4cc(C)no4)ccc3C)CC2)c1
b) COc1ccc(C)cc1S(=O)(=O)N1CCCC(C(=O)N2CCN(c3ccccc3F)CC2)C1
c) Cc1c(/C=N/NC(=O)C(C)(C)Oc2ccc(Cl)cc2)cnn1C
d) O=C(c1ccccc1)N1CCN(c2ccc([N+](=O)[O-])c(NCC3CCCO3)c2)CC1
Answer: d. O=C(c1ccccc1)N1CCN(c2ccc([N+](=O)[O-])c(NCC3CCCO3)c2)CC1
