Task: Answer the multiple choice question.
Query: Which compound has a 13.001\% 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. CSC1=N/C(=C\c2cccc(F)c2)C(=O)S1
b. CC(=O)Nc1ccc(S(=O)(=O)NC(C)c2nc(-c3ccccc3)no2)cc1
Answer: a. CSC1=N/C(=C\c2cccc(F)c2)C(=O)S1
