Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.448\% 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(=O)(=O)NC2CCCC2)c(OC)cc1Cl
b Cc1ccsc1C1CC(=O)NC2=C1C(=O)CC(C)(C)C2
Answer: a. COc1cc(S(=O)(=O)NC2CCCC2)c(OC)cc1Cl
