Task: Answer the multiple-choice question.
Question: Which drug exhibits a 31.321% 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) CC(=O)N/N=C(\C)c1ccc(Br)cc1Br
(b) COc1ccc(-c2nc(CS(=O)CC(=O)NCc3ccco3)c(C)o2)cc1OC
Answer: a. CC(=O)N/N=C(\C)c1ccc(Br)cc1Br
