C

Step 1: Understand that the height (h) of a projectile varies with time (t) in a parabolic manner.
Step 2: When a projectile is launched from the ground, it rises to a maximum height and then falls back to the ground.
Step 3: The correct graph representing this relationship will start from the origin (0,0), rise to a peak (maximum height), and then return back to zero (ground level), forming a parabolic arc.
Step 4: Among the given options, Option C accurately depicts this behavior of height versus time for a projectile.
Therefore, C.
