I'll paraphrase the question: There is a pallet with tomato cases on it and it is being lifted by a crane. Find the center of gravity in the horizontal plane so that the crane operator can pick up the load without tipping it.
What does it mean by "find the center of gravity in the horizontal plane"? Does it mean just find the Xcm? Or do I have to consider Ycm and Zcm as well?

I believe they are looking for the coordinates of (Xcm,Ycm).

The actual 'center of mass' will be somewhere above the pallet (since the cases are stacked up on it) but the 'tipping' axis will be the x and y axis throught the pallet.
You need to find the x and y coordinates of the CG location as projected 'down' onto the pallet.

Just X and Y--the hook of the crane needs to be in line with the (pallet+crate) CM and the center of the earth, otherwise the pallet will tip and the crate will slide off. Z is changing--after all, the crane is lifting the pallet upwards.

Just point out the centre of mass as you will see it when viewing from the top (a plan view). You dont have to bother about the vertical axis.
