Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 14.478\% 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(Nc1nc(-c2ccccc2)cs1)c1ccccc1F
b: COc1ccc(/C=C(/Sc2nnc(-c3ccc(Cl)cc3)o2)C(=O)O)cc1
Answer: a. O=C(Nc1nc(-c2ccccc2)cs1)c1ccccc1F
