Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.672\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COC(=O)[C@H](Cc1ccccc1)NC(=O)NCCc1ccc(S(N)(=O)=O)cc1
[b] N=c1sc2ccccc2n1-c1ccccc1
Answer: a. COC(=O)[C@H](Cc1ccccc1)NC(=O)NCCc1ccc(S(N)(=O)=O)cc1
