Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.650\% 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) COc1ccc(NC(=O)CN(C)C(=O)c2cnc(Cl)c(Cl)c2)cc1
b) O=S1(=O)C=CC(Nc2cccc(Cl)c2)C1
Answer: b. O=S1(=O)C=CC(Nc2cccc(Cl)c2)C1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
