Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.024\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] C=CCn1c(=O)c(C(=O)NC(C)c2ccccc2)c(O)c2ccccc21
[b] CCOc1ccccc1NC(=O)NC(=O)N(C)S(C)(=O)=O
Answer: b. CCOc1ccccc1NC(=O)NC(=O)N(C)S(C)(=O)=O
