Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.450\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COc1ccccc1NC(=O)CN(C)S(=O)(=O)c1cc(C)ccc1OC
b COc1ccc(CCn2c(N)c(C(=O)NCc3ccco3)c3nc4ccccc4nc32)cc1OC
Answer: a. COc1ccccc1NC(=O)CN(C)S(=O)(=O)c1cc(C)ccc1OC
