Task: Answer the multiple choice question.
Question: Which drug has a 2.490% 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: CCOC(=O)c1cc2n(c1/N=C/N(C)C)-c1ccccc1C2=O
b: CN(C)c1ccc(C(=S)N2CCCCC2)cc1
Answer: a. CCOC(=O)c1cc2n(c1/N=C/N(C)C)-c1ccccc1C2=O
