Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.900\% 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.) O=C1CC(NS(=O)(=O)c2cccs2)CN1c1ccc(F)cc1
b.) CC(=O)Nc1ccc(C(=S)NCCCO)cc1
Answer: a. O=C1CC(NS(=O)(=O)c2cccs2)CN1c1ccc(F)cc1
