Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.270\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1cc(NS(=O)(=O)c2ccc(NC(=O)C(C(C)C)N3C(=O)c4ccccc4C3=O)cc2)nc(C)n1
b: COc1ccc(-c2csc(NC(=S)NC(=O)c3ccc4ccccc4c3)n2)cc1OC
Answer: b. COc1ccc(-c2csc(NC(=S)NC(=O)c3ccc4ccccc4c3)n2)cc1OC
