Correct answer · Option 4
A-(II), B-(I), C-(IV), D-(III)
Explanation
Average velocity is displacement over time interval \( \frac{\Delta x}{\Delta t} \). Instantaneous acceleration is \( \lim_{\Delta t \to 0} \frac{\Delta v}{\Delta t} \). Stopping distance is \( \frac{v_0^2}{2a} \). Reaction time is \( \sqrt{\frac{2d}{g}} \).
