Match List-I with List-II:
| List-I (1D Motion Graph Anomaly) | List-II (Physical Impossibility Reason) | ||
|---|---|---|---|
| A | Total path length decreasing with time | I | Speed is intrinsically non-negative |
| B | Speed vs time graph with negative values | II | Total distance traversed can never decrease |
| C | Position-time graph forming a closed loop | III | Particle would have two velocities at the same instant |
| D | Velocity-time graph forming a closed loop | IV | Particle would occupy two positions at the same instant |

Correct answer · Option 4
A-(II), B-(I), C-(IV), D-(III)
Explanation
Total distance traversed can never decrease with time. Speed is the magnitude of velocity and must be non-negative. A closed loop in x-t graph implies two positions at one time, and in v-t graph implies two velocities at one time.
