A sphere falling in a viscous liquid increases its speed with time and finally achieves a terminal velocity at infinite time.
Velocity varies with time as shown.
Net acceleration of the sphere is (Buoyant force-Viscous Force) downwards
Hence a varies linearly with velocity. Hence option C is the correct answer.
