The correct statement is: "Harshitha’s Average Velocity is -2.5 m/s".

Here's the step by step explanation:

1. Velocity is a vector quantity, which means it has both magnitude (speed) and direction. In this case, Harshitha is moving from a positive position (x = 8 m) to a negative position (x = -12 m), which indicates a negative direction.

2. To calculate the velocity, we subtract the final position from the initial position and divide by the time it took. So, (-12 m - 8 m) / 8 s = -20 m / 8 s = -2.5 m/s. The negative sign indicates the direction of the velocity, so Harshitha’s Average Velocity is -2.5 m/s.

3. Speed, on the other hand, is a scalar quantity, which means it only has magnitude and no direction. Therefore, speed cannot be negative. So, the statement "Harshitha’s Average Speed is -2.5 m/s" is incorrect.

4. The statement "Harshitha’s Velocity is -2.5 m/s" is also incorrect because it doesn't specify that this is an average velocity over the 8 seconds.

5. The statement "Harshitha’s Average Velocity is 2.5 m/s" is incorrect because it doesn't take into account the negative direction of the movement.
