Task: Answer the multiple choice question.
Query: Which compound has a 1.257% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C(Nc1nccs1)c1ccc(COc2c(F)c(F)cc(F)c2F)o1
b. CC(C)NC(=O)COC(=O)c1ccccc1CSC1=NCCS1
Answer: a. O=C(Nc1nccs1)c1ccc(COc2c(F)c(F)cc(F)c2F)o1
