To determine when the child has the greatest potential energy, we need to consider the concept of gravitational potential energy, which is typically calculated using the formula:
\[ PE = mgh \]
where:
- \( PE \) is the potential energy,
- \( m \) is the mass of the object (the child, in this case),
- \( g \) is the acceleration due to gravity, and
- \( h \) is the height above a reference point.
In general, the potential energy is greatest when the child is at the highest point. Therefore, without additional context (like a description of a scenario), we can infer that the child will have the greatest potential energy at the highest point they reach.
If options represent different heights or positions, select the option corresponding to the highest position. If additional information is provided in the rest of the content not seen here, it would help clarify the answer further.
