Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.346\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCCS(=O)(=O)N1CCN(Cc2ccc([N+](=O)[O-])cc2)CC1.O=C(O)C(=O)O
b CC(C)N1CCN(Cc2coc3ccccc3c2=O)CC1CCO
Answer: a. CCCS(=O)(=O)N1CCN(Cc2ccc([N+](=O)[O-])cc2)CC1.O=C(O)C(=O)O
