Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.752\% 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: NS(=O)(=O)c1ccc(CCNC(=O)Nc2ccc(Cl)c(Cl)c2)cc1
b: Cc1nn(CCC(=O)NCc2ccc(OC(C)C)cc2)c(=O)c2nn(-c3ccccc3)c(C)c12
Answer: a. NS(=O)(=O)c1ccc(CCNC(=O)Nc2ccc(Cl)c(Cl)c2)cc1
