Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The escape velocities of planet A and B are same. But A and B are of unequal mass.
Reason $\displaystyle \mathbf{R}$ : The product of their mass and radius must be same. $\displaystyle \mathrm{M}_1 \mathrm{R}_1=\mathrm{M}_2 \mathrm{R}_2$
In the light of the above statements, choose the most appropriate answer from the options given below :
