Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.025\% 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.) COc1ccccc1NS(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
b.) COc1cccc(N(CC(=O)NCc2cccnc2)S(C)(=O)=O)c1
Answer: a. COc1ccccc1NS(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
