Task: Answer the multiple choice question.
Question: Which compound has a 4.030\% 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: COc1cc(C2C(C#N)=C(N)Oc3c2c(-c2ccccc2)nn3-c2ccccc2)cc(OC)c1OC
b: Cc1nc(SCC(=O)Nc2ccc(C(F)(F)F)cc2)c2c(=O)n(C)c(=O)n(C)c2n1
Answer: b. Cc1nc(SCC(=O)Nc2ccc(C(F)(F)F)cc2)c2c(=O)n(C)c(=O)n(C)c2n1
