Task: Answer the multiple-choice question.
Query: Which compound exhibits a 14.613\% 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, or c without using any other words.
Options:
[a] O=C(/C=C/c1cccs1)NCc1ccc2c(c1)OCO2
[b] COc1ccccc1C(=O)NCC1(c2ccccc2)CCCC1
[c] CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)c2ccccc2C(=O)c2ccc(Cl)c([N+](=O)[O-])c2)cc1
Answer: b. COc1ccccc1C(=O)NCC1(c2ccccc2)CCCC1
