Answer

c)

Work Step by Step

It is greater for the trunk. After all, because gravity is a conservative force, the work to get them up to the same point at the top of the curved path will be the same. However, the negative work of friction will still be greater for the trunk, so it will require more work to get the trunk to the same point.
