S= ut + 0.5 a (t)^2.
here S=0, since range is horizontal distance covered until the particle reached the its initial point.
overall angle of projection = (α-β).
accelaration (a) = g*cosβ , since inclination of the plane is present.
u = intial velocity in x direction = usin(α-β).
Substitute all the values in the equation. You will get the answer.

This answer will be possible only when projectile motion normal to the inclined plane, where displacement is zero.

There's no range (distance) given in the options.

When inclination is increased automatically the time of flight increases there by the denominator should be minimum.

What is time of flight define? Please.

@K.Kisku.
While throwing an object, the time taken by the object to reach rest or destination.

The total time taken by a projectile to reach the maximum height and to return back to ground is known as the time of flight.

Rotate your coordinate axis by beta degrees and resolve your "g" component in your new axis.
Your displacement in y-axis will be given as.
y = usin (a-b) - 0.5cos (b) t^2.
After a time of flight T displacement along y-axis will be zero places y = 0 in the equation, you will get the answer.

According to me, the answer is (2ucos(a))/(gcos(b)).

Here the angle of projection is also from horizontal.
