Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 5.560\% 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, or d without using any additional words.
Options:
a: COc1cccc(CN(C)C(=O)c2ccc(N3CCCC3)c([N+](=O)[O-])c2)c1
b: CCCCOc1ccc(C(=O)NCC(=O)N2CCN(C(=O)c3ccco3)CC2)cc1
c: CC1(C(=O)Nc2nccs2)Cc2ccccc2C(=O)O1
d: CC(C)CNC(=O)/C=C/C(=O)O
Answer: a. COc1cccc(CN(C)C(=O)c2ccc(N3CCCC3)c([N+](=O)[O-])c2)c1
