Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.696\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cn1nc(C(F)(F)F)c(C(=O)Nc2cccc(Cl)c2)c1Cl
b. CCOc1ccc(C(C(=O)NC2CCCC2)N(C(=O)CNC(=O)c2ccco2)c2cccnc2)cc1
c. Cc1onc(-c2ccccc2Cl)c1C(=O)Nc1sc2c(c1C#N)CCC2
Answer: a. Cn1nc(C(F)(F)F)c(C(=O)Nc2cccc(Cl)c2)c1Cl
