Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.901\% 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(CSc1nc(-c2ccccc2)cc(=O)[nH]1)Nc1ccc(F)c(F)c1
b: O=C(N/N=C/c1c(Cl)cccc1Cl)c1ccccc1F
Answer: a. O=C(CSc1nc(-c2ccccc2)cc(=O)[nH]1)Nc1ccc(F)c(F)c1
