Task: Answer the multiple-choice question.
Question: Which compound exhibits a 18.929\% 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)C1=C(CS(=O)(=O)c2ccccc2)NC(=O)NC1c1ccc(OC)c(OC)c1
b) CC(/C=N/NC(=O)c1cnccn1)=C\c1ccco1
Answer: a. COC(=O)C1=C(CS(=O)(=O)c2ccccc2)NC(=O)NC1c1ccc(OC)c(OC)c1
