Assertion (A) : The area bounded by ${\mathrm{y}}^2=8\mathrm{x}$ and ${\mathrm{x}}^2=8\mathrm{y}$ is $\frac{64}{3}$sq. units.

Reason (R) : The area bounded by ${\mathrm{y}}^2=4\mathrm{ax}$ and ${\mathrm{x}}^2=4\mathrm{by}$ is $\frac{16\mathrm{ab}}{3}$ sq. units.

The correct answer is

Both (A) and (R) are true and R is the correct explanation of A

Both (A) and (R) are true and R is not the correct explanation of A

(A) is true, (R) is false
