Task: Answer the multiple choice question.
Question: Which compound has a 3.453\% 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) CN(CC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1)C(=O)c1cccc(N2C(=O)CCC2=O)c1
(b) Nc1ncnc(N2CCOCC2)c1N
(c) O=C(CCc1ccc(S(=O)(=O)NCCc2ccccc2)cc1)Nc1ccc2c(c1)OCCO2
(d) COc1cc(NC(=O)/C=C/c2ccccc2)c(C(=O)O)cc1OC
Answer: a. CN(CC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1)C(=O)c1cccc(N2C(=O)CCC2=O)c1
