Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.277\% 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 or b without using any other words.
Options:
(a) COc1ccc2c(c1)CCc1c(C(=O)NCc3ccc(Cl)cc3)noc1-2
(b) Cc1c(C(=O)NN)nn(-c2ccc(F)cc2)c(=O)c1C#N
Answer: b. Cc1c(C(=O)NN)nn(-c2ccc(F)cc2)c(=O)c1C#N
