Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.399\% human ether-à-go-go related gene (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.) O=c1[nH]cnc2c1c(-c1ccccc1)cn2-c1ccccc1
b.) O=C(NCC(=O)N1CCCCC1)c1ccc2ccccc2c1
c.) CCc1ccc(NC(=O)CN(c2cc(C)cc(C)c2)S(=O)(=O)c2c(C)[nH]c(=O)[nH]c2=O)cc1
d.) Cc1nc2nc(SCc3ccc([N+](=O)[O-])cc3)[nH]c2cc1Br
e.) CCCCn1c(N)c(N(CCC(C)C)C(=O)CC2CCCC2)c(=O)[nH]c1=O
Answer: e. CCCCn1c(N)c(N(CCC(C)C)C(=O)CC2CCCC2)c(=O)[nH]c1=O
