Task: Answer the multiple-choice question.
Question: Which compound exhibits a 1.369\% 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 other words.
Options:
a: CCn1nc([N+](=O)[O-])c2c(-c3nc4ccccc4o3)c(N)n(CCCOC)c2c1=O
b: CCOc1ccc(S(=O)(=O)Nc2ccc(C(=O)N3CCCC3)cc2)cc1C(N)=O
c: COc1ccccc1-c1c(C#N)c(N)nc2c1CCc1ccccc1-2
d: CCOC(=O)N1CCN(C(=O)c2cc3c(=O)[nH]c4ccccc4c3s2)CC1
e: CCCCn1c(SCC(=O)NC2CC2)nc2ccccc2c1=O
Answer: e. CCCCn1c(SCC(=O)NC2CC2)nc2ccccc2c1=O
