Balanced reaciton: 

2 N2H4 (g) + N2O4 (g) → 3N2(g) + 4H2O(g)

To have a proper visualization, we must assign the colors to specific atoms so that we know what we are looking at.

Blue = N (Since it is in the middle of the molecules)
White = H (slightly smaller)
Red = O

Problem Details

Consider the following reaction: 2N2H4 (g) + N2O4 (g) → 3N2(g) + 4H2O(g) Consider the following representation of an initial mixture of N2H4 and N2O4 : A space-filling molecular diagram which is a collection of six molecules composed of two blue spheres combined surrounded by four smaller white spheres (two on each blue sphere), and four molecules composed of two blue spheres combined surrounded by four red spheres (two on each blue sphere).

Which of the following best represents the reaction mixture after the reactants have reacted as completely as possible? Three space-filling molecular diagrams labeled a, b, and c. Diagram a is a collection of one molecule composed of two blue spheres combined surrounded by four red spheres (two on each blue sphere), nine molecules composed of two blue spheres combined, and eleven molecules composed of a central red sphere surrounded by two smaller white spheres. Diagram b is a collection of two molecules composed of two blue spheres combined surrounded by four red spheres (two on each blue sphere), twelve molecules composed of two blue spheres combined, and sixteen molecules composed of a central red sphere surrounded by two smaller white spheres. Diagram c is a collection of nine molecules composed of two blue spheres combined, and twelve molecules composed of a central red sphere surrounded by two smaller white spheres.
