Answer:

The correct equation showing the decomposition of #"NO"_2# is:

#"2NO"_2("g")##rarr##"2NO(g) + O"_2("aq")#

Explanation:

We can know it's a decomposition reaction because a single reactant forms two simpler products. In this case, the #"NO"_2"# loses oxygen. For every two moles of #"NO"_2# decomposed, two moles of oxygen atoms are lost, which form one mole of oxygen gas #("O"_2")#.
