Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.707% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCC(=O)Nc1ccc(C(=O)CSc2nnc(-c3ccccc3F)n2CCc2ccccc2)cc1
b) O=C(COC(=O)c1cccnc1Cl)NCc1cccs1
Answer: b. O=C(COC(=O)c1cccnc1Cl)NCc1cccs1
