To describe a model of methanol (CH3OH), we need to identify the types and amounts of atoms present in the molecule:

  • Carbon (C): 1 atom
  • Hydrogen (H): 3 atoms
  • Oxygen (O): 1 atom
  • Hydrogen (H): 1 atom from the hydroxyl group, which adds up to 4 hydrogen atoms in total.

Now, we can summarize the molecular composition:

  • 1 gray sphere (for Carbon)
  • 4 white spheres (for 4 Hydrogen)
  • 1 red sphere (for Oxygen)

Putting this together, the correct description of methanol (CH3OH) is: one gray sphere, four white spheres, one red sphere.

Therefore, the correct option is: one gray sphere, four white spheres, one red sphere.
