Task: Answer the multiple choice question.
Query: Which compound exhibits a 19.738% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C1c2ccccc2C(=O)N1CCSc1ncn[nH]1
b. O=C(O)C(c1ccccc1)N1C(=O)/C(=C\c2ccc(-c3cccc(Cl)c3)o2)SC1=S
Answer: a. O=C1c2ccccc2C(=O)N1CCSc1ncn[nH]1
