Task: Answer the multiple choice question.
Question: Which drug has a 15.091\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC(C)CCC1(CN2CCCC2=O)C(=O)NC(=O)NC1=O
b. C=CCN1CN(S(=O)(=O)c2cccc(Cl)c2)c2nc3ccccc3nc21
Answer: b. C=CCN1CN(S(=O)(=O)c2cccc(Cl)c2)c2nc3ccccc3nc21
