The angle in which a cricket ball should be hit to travel

The angle in which a cricket ball should be hit to travel maximum horizontal distance is :

1. 60° with horizontal
2. 45° with horizontal
3. 30° with horizontal
4. 15° with horizontal

This has to do with the equation of a parabola or
trajectory which is

z = (tanθ)x -	θ	x²
	2(cosθ)

We can see that if the ball is fired at a 45 degree angle from the ground, the horizontal distance will be a maximum.
