Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.472\% human ether-à-go-go related gene (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 CC(=O)c1sc(NC(=O)c2c(F)cccc2F)nc1-c1ccccc1
b COc1ccc(C2=NCC(CSc3nnc(-c4ccc5c(c4)OCO5)o3)S2)cc1
Answer: a. CC(=O)c1sc(NC(=O)c2c(F)cccc2F)nc1-c1ccccc1
