Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.569% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(COc1ncnc2scc(-c3ccccc3)c12)NCCN1C(=O)CSC1=O
b: COc1ccc(C2NC(c3ccc(OC)c(OC)c3OC)C(C)C(=O)C2C)c(OC)c1OC.Cl
Answer: a. O=C(COc1ncnc2scc(-c3ccccc3)c12)NCCN1C(=O)CSC1=O
