Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.456\% 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] CCCN(CC(=O)Nc1ccccc1C)C(=O)c1ccc(S(=O)(=O)N2CCCCCC2)cc1
[b] Cl.O=C(Nc1cc(F)cc(F)c1)c1ccc(NCCCN2CCCCCC2)c([N+](=O)[O-])c1
Answer: a. CCCN(CC(=O)Nc1ccccc1C)C(=O)c1ccc(S(=O)(=O)N2CCCCCC2)cc1
