Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.511\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(CC(c1ccccc1)c1cc(Cl)ccc1O)NCCCN1CCOCC1
b. CC(C)NC(=O)COc1ccc(S(=O)(=O)N2CCCC2)cc1
c. Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)NCc1ccc(Cl)cc1
Answer: c. Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)NCc1ccc(Cl)cc1
