The correct answer is $\boxed{\text{B. }0.50}$.
The kinematic viscosity is defined as the dynamic viscosity divided by the density of the fluid. The dynamic viscosity is given as 0.5 poise, and the specific gravity is given as 0.5. The density of a fluid is equal to its specific gravity times the density of water, which is 1 g/mL. Therefore, the density of the fluid is 0.5 g/mL. The kinematic viscosity is then equal to 0.5 poise / 0.5 g/mL = 0.5 stokes.
Option A is incorrect because it is the dynamic viscosity, not the kinematic viscosity. Option C is incorrect because it is the dynamic viscosity divided by the specific gravity, not the kinematic viscosity. Option D is incorrect because it is not one of the possible answers.
