1. Movement Analysis:
- When a camel stands up, its motion involves lifting its hind legs first, followed by the front legs.
- Point \(P\), located on the camel's body, will trace an arc-like trajectory as the camel’s body lifts and shifts forward.
2. Options Analysis:
- Option A: This does not represent the realistic trajectory of \(P\), as it assumes a straight vertical movement.
- Option B: This correctly traces the curved arc movement of \(P\) as the camel rises by lifting its hind legs first and then its front legs. Hence, \(B\) is correct.
- Option C: This trajectory does not account for the forward movement of the camel during standing.
- Option D: This trajectory is unrealistic, assuming backward movement of the camel during standing.
Conclusion: The correct trajectory of \(P\) is represented by \(B\).
