Task: Answer the multiple choice question.
Question: Which compound has a 4.991% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Cn1c(CNC(=O)CCNC(=O)c2cccc(Br)c2)cc(=O)n(C)c1=O
b CC(C)(C)NC(=O)CN(Cc1cccs1)C(=O)CNS(=O)(=O)c1ccccc1
Answer: a. Cn1c(CNC(=O)CCNC(=O)c2cccc(Br)c2)cc(=O)n(C)c1=O
