Task: Answer the multiple-choice question.
Question: Which drug exhibits a 23.551\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COc1cc(S(N)(=O)=O)c(OC)cc1N
(b) COC(=O)NNC(=O)COc1ccc(Cl)cc1
Answer: a. COc1cc(S(N)(=O)=O)c(OC)cc1N
