Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.383% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCCCCC(=O)NNC(=O)Cc1ccc([N+](=O)[O-])cc1
b: O=C1CC(c2ccc3ccccc3c2)NN1
c: NC(=O)c1ccc(NC(=O)COC(=O)c2cc([N+](=O)[O-])ccc2N2CCOCC2)cc1
Answer: a. CCCCCC(=O)NNC(=O)Cc1ccc([N+](=O)[O-])cc1
