Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.904% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CSc1nc(O)c(N=Nc2ccc(F)cc2F)c(=O)[nH]1
b CCOC(=O)Cn1c(SC)nc2sc3c(c2c1=O)CC(C)(C)OC3
Answer: a. CSc1nc(O)c(N=Nc2ccc(F)cc2F)c(=O)[nH]1
