Sheet will look like this, you can notice that now years are displayed horizontally and products are displayed vertically
Now select the Sales measure and drag it to Text option as shown below
Now you can see the sales for all product for all years
Since in the question, it is asked to find the percentage difference of growth in sales across product sub categories across years, for this we shall use the Quick Table Calculations.
In order to use the table calculations, right click on the Sales measure and select the option as shown below
As soon as you select this option, your values will be changed and will reflect the percentages across all years.
Notice that a small arrow sign has started appearing on the Sales measure, this is sign of Quick Table calculations.

Now by seeing the data, it can be very easily identified that product sub category Scissors, Rulers and Trimmers has highest percentage of growth across all years.
So the answer for this question is Scissors, Rulers and Trimmers.
