Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.839\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CN1CCc2nc(SCC(=O)Nc3ccc(OC(F)(F)F)cc3)c(C#N)c(-c3cccs3)c2C1
b) CC(C)CN1C(=O)c2ccc(NC(=O)c3cccs3)cc2C1=O
Answer: b. CC(C)CN1C(=O)c2ccc(NC(=O)c3cccs3)cc2C1=O
