Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.305\% 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 other words.
Options:
(a) COc1cccc(NC(=O)Cn2c(CCC(=O)O)ccc2-c2ccc(Cl)cc2)c1
(b) COc1ccccc1CNC(=O)c1sccc1-c1ccccc1
(c) CCOC(Cn1ccc(=O)[nH]c1=O)OCC
(d) Cc1ccnn1-c1ccc(C(=O)NCC(c2ccco2)N2CCCC2)cc1
Answer: c. CCOC(Cn1ccc(=O)[nH]c1=O)OCC
