Task: Answer the multiple choice question.
Query: Which compound has a 4.345% 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] CCCC(=O)Nc1nc2ccc(S(N)(=O)=O)cc2s1
[b] COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)c(OC)c1OC
Answer: b. COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)c(OC)c1OC
