Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 8.929\% 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 additional words.
Options:
a CCCn1c(N)c(N(CCOC)C(=O)CSc2cc(C)c3cccc(C)c3n2)c(=O)[nH]c1=O
b Cc1ccc(C(=O)Nc2cccc(C(=O)NCc3ccccc3)c2)cc1
c CCCCCCN1C=CC(=C/C=C(\C#N)C(=O)OCC)C=C1
d CC(=O)NCCc1c[nH]c2ccc(O)cc12
e CCC(=O)Nc1cccc(C(=O)Nc2nccs2)c1
Answer: c. CCCCCCN1C=CC(=C/C=C(\C#N)C(=O)OCC)C=C1
