Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.421% 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.) CCN1C(=S)N[C@@H](c2cccs2)C(C(=O)OC)=C1C
b.) Cc1cc(=O)n(Cc2ccccc2)c2ccccc12
Answer: a. CCN1C(=S)N[C@@H](c2cccs2)C(C(=O)OC)=C1C
