Explanation:

Let’s look at the options in simple terms:

- Dispersion Forces (Option 1)

These are also called London forces. They’re present in all molecules, but especially in nonpolar ones. They come from tiny, momentary shifts in electron clouds, creating temporary dipoles that stick molecules together.

- Dipole-Induced Dipole Forces (Option 2)

These happen when a polar molecule messes with a neighboring nonpolar molecule’s electron cloud, creating a short-term dipole in the nonpolar one.

- Dipole-Dipole Forces (Option 3)

That’s when two polar molecules attract each other because their positive and negative ends line up.

- Hydrogen Bond Forces (Option 4)

These are a special kind of dipole-dipole force, much stronger, and happen when hydrogen bonds to electronegative atoms like O, N, or F.

So, yeah, London forces are the same as dispersion forces. You nailed it.
