Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.926\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CN1C(=O)CC(C(=O)O)SC1=Nc1cccc(C(F)(F)F)c1
b O=S(=O)(NCc1ccc2c(c1)OCO2)c1cccc2cccnc12
Answer: a. CN1C(=O)CC(C(=O)O)SC1=Nc1cccc(C(F)(F)F)c1
