Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.745\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COC(=O)C1=C(O)CSC1=Nc1cccc(C(F)(F)F)c1
[b] CN(C)C(=O)CSc1nc2ccccc2c(=O)[nH]1
Answer: a. COC(=O)C1=C(O)CSC1=Nc1cccc(C(F)(F)F)c1
