B. Sled B has more potential energy.

Explanation:

Option B is correct because when you carry out the calculation, you will find out.

Below is the calculation:

Potential energy = mgh where m= mass of sled, g=gravitational force = $9.8m/s^{2}$ and h= height.

Sled A Potential Energy = 100kg x $9.8m/s^{2}$ x 50m = $49000kgm^{2}/s^{2}$ = 49kJ.

Sled B Potential Energy = 200kg x $9.8m/s^{2}$ x 30m = $58800kgm^{2}/s^{2}$ = 58.8kJ.

So, since Sled B gave us 58.8kJ, it has more potential energy than Sled A that has 49kJ.
