Final answer:
The similarity parameters are speed and acceleration.
Step-by-step explanation:
The similarity parameters among the options are speed and acceleration (Option D).
Speed is a scalar quantity that measures how fast an object is moving, regardless of its direction. Acceleration is a vector quantity that measures the rate of change of velocity, which includes both speed and direction.
For example, when a car is driving at a constant speed, the speed remains the same, but if it changes its direction or increases/decreases its speed, the acceleration will be different.
