Essential Condition for Horizontal Component of Projectile to Remain Constant
The motion of a projectile can be broken down into two components - horizontal and vertical. The horizontal component of motion remains constant throughout the motion of the projectile if there is no external force acting on it. This is known as the principle of inertia. The essential condition for the horizontal component of the projectile to remain constant is:
No Air Resistance
When a projectile is projected with a certain velocity, it experiences air resistance which opposes its motion. The resistance increases with the increase in velocity and can cause a change in the horizontal component of the projectile's motion. Therefore, for the horizontal component of the projectile to remain constant, there should be no air resistance acting on it. This condition is practically not possible as air resistance is always present in the atmosphere. However, for small distances and at low velocities, the effect of air resistance can be neglected.
The Effect of Air Resistance
Air resistance has a significant effect on the motion of a projectile. It opposes the vertical motion of the projectile, reducing its height and increasing the time of flight. It also opposes the horizontal motion of the projectile, reducing its range. Hence, in real-world scenarios, the horizontal component of a projectile's motion is not constant.
Conclusion
In conclusion, the essential condition for the horizontal component of a projectile to remain constant is the absence of air resistance. However, in real-world scenarios, air resistance is always present and affects the projectile's motion. Therefore, the horizontal component of a projectile's motion is not constant in practical situations.

The horizontal component of velocity remains constant for any angle of projection.
And g is not acting horizontally. .so it is not necessary to be constant.
Air resistance should be absent..
So..ans is C.
