Task: Answer the multiple-choice question.
Question: Which compound has a 8.989\% 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) COc1ccc(C(C(=O)NCC2CCCO2)N(C(=O)CNC(=O)c2ccco2)c2ccc(C)c(C)c2)cc1OC
(b) CC(Sc1nnc(CN2CCCC2)n1Cc1ccccc1)C(=O)Nc1ccccc1
(c) O=C(Nc1ncc2c(n1)-c1ccccc1OC2)c1ccccc1Cl
Answer: c. O=C(Nc1ncc2c(n1)-c1ccccc1OC2)c1ccccc1Cl
