Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.450\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(CSc1nc(N2CCCCC2)nc(N2CCCCC2)n1)Nc1nccs1
b: COc1ccc(S(=O)(=O)N2CCC3(CC2)OCCN3S(=O)(=O)c2c(C)cc(C)cc2C)cc1
c: COc1cccc(N2CC(O)Cn3c2nc2c3c(=O)[nH]c(=O)n2C)c1
d: O=c1[nH]c(Nc2ccc3c(c2)OCCO3)nnc1Cc1ccccc1
e: O=C(COc1cccnc1[N+](=O)[O-])NCc1cccs1
Answer: e. O=C(COc1cccnc1[N+](=O)[O-])NCc1cccs1
