Task: Answer the multiple choice question.
Question: Which compound exhibits a -11.724\% 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 other words.
Options:
[a] O=C(CN1CCOCC1)Nc1ccc([N+](=O)[O-])cc1Br
[b] Cc1nn(C)c(C)c1NC(=O)/C(C#N)=C\N(C)C
[c] CN1CCCC(OC(=O)CCCC(=O)OC2CCCN(C)C2)C1.Cl
Answer: a. O=C(CN1CCOCC1)Nc1ccc([N+](=O)[O-])cc1Br
