Solution:
Thinner is a solvent added to paint to reduce its viscosity, making it easier to apply.
Let's look at the options:
Option A: Naphtha - Naphtha can be used as a solvent, but it is not as common as turpentine in oil paints.
Option B: Turpentine - Turpentine is a widely used and very effective thinner for oil paints.
Option C: Both (A) and (B) - Since Turpentine is more commonly used, this option is a possibility.
