C# :: Populate Labels With A List Or Array?

I have a WPF grid made out of labels with two rows, Apples and Oranges currently without any information. Let's say I want to populate the grid to look like the picture below.

I was wondering what's the best way to populate the labels with a list or array? I was thinking about using a list and passing values into the list

E.g.

List <string> ApplesList = new List<string>();
ApplesList.Add("Red");
ApplesList.Add("Delicious"):

List<string> OrangesList = new List<string>();
OrangesList.Add("Orange");

etc...

But I was wondering it make sense to use a list. Or should I just use an array or 2D array?

Sometimes I wonder when would be best to use a list, array, or 2D array.
