Task: Answer the multiple choice question.
Question: Which compound exhibits a 11.067\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC(CCc1ccccc1)NC(=O)COC(=O)c1cccs1
b: CCCc1[nH]c(=O)c(C#N)c2c1CCCC2
c: CCOc1ccc(Nc2nc(C)cc(C)c2C#N)cc1
d: CC(CN1CCCCC1)OC(=O)COc1ccc(Cl)cc1.Cl
Answer: c. CCOc1ccc(Nc2nc(C)cc(C)c2C#N)cc1
