Task: Answer the multiple choice question.
Query: Which compound exhibits a -6.217\% 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 additional words.
Options:
a: O=C(Nc1nnc(-c2ccccc2)s1)c1ccccc1O
b: Cc1sc2ncnc(NC(C)C(=O)O)c2c1C
Answer: a. O=C(Nc1nnc(-c2ccccc2)s1)c1ccccc1O
