Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.569\% 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: CCOC(=O)/C(N=Nc1ccc(C(=O)O)cc1[N+](=O)[O-])=C(\C)O
b: CCCCCC(=O)NCc1c(C(F)(F)F)nn(C)c1N1CCOCC1
c: COc1ccc(C2CCCN2C(=O)Nc2ccc(Cl)cc2)cc1OC
Answer: a. CCOC(=O)/C(N=Nc1ccc(C(=O)O)cc1[N+](=O)[O-])=C(\C)O
