Explanation:

Step1: Identify the shortest bar

By observing the bar - chart, the bar for red color is the shortest. The height of the red - color bar represents 2 T - shirts sold.

Step2: Find the number of black and white T - shirts

The number of white T - shirts sold is 4 (height of the white bar), and the number of black T - shirts sold is 6 (height of the black bar). Then, calculate the difference: $6 - 4=2$.

Step3: Count the number of colors with more than 2 T - shirts sold

White (4 T - shirts), blue (8 T - shirts), black (6 T - shirts), and yellow (8 T - shirts) have more than 2 T - shirts sold. So there are 4 such colors.

(a) red, 2
