Task: Answer the multiple-choice question.
Query: Which drug has a 5.439\% 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) CC(CS(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCOCC1
b) O=C(NCCN1CCOCC1)c1sc2ccccc2c1Cl
Answer: a. CC(CS(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCOCC1
