Task: Answer the multiple-choice question.
Question: Which drug exhibits a 18.349\% 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 other words.
Options:
a COC(=O)Cc1ccc(NC(=S)NCc2ccccc2)cc1
b C/C(=N\NC(=O)c1cc(-c2ccc(C)s2)[nH]n1)c1ccncc1
c C=CCn1c(-c2cc(-c3ccc(C)cc3)nc3ccccc23)n[nH]c1=S
d Nc1c(C(=O)NCc2ccco2)sc2nc3c(cc12)C(=O)CCC3
e CCCCCc1nnc(NC(=O)Cc2ccc([N+](=O)[O-])cc2)s1
Answer: e. CCCCCc1nnc(NC(=O)Cc2ccc([N+](=O)[O-])cc2)s1
