Task: Answer the multiple choice question.
Question: Which compound exhibits a 11.875\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCN(CC(=O)NCc1cccs1)S(=O)(=O)c1cccc(Br)c1
b: Cc1nc(CS(=O)c2ccc(Cl)cc2)cc(NCc2ccc(Cl)cc2Cl)n1
Answer: a. CCN(CC(=O)NCc1cccs1)S(=O)(=O)c1cccc(Br)c1
