The histogram shows the distribution of tree diameters measured in centimeters, with a range of diameters from 0 to 55 cm and their respective frequencies.

From the histogram:

• The majority of the tree diameters fall between 5 and 25 cm, forming a cluster.
• There is a noticeable gap between 25 and 40 cm where the frequencies are very low.
• Another smaller cluster exists around 45 to 50 cm.

This indicates that the distribution is not continuous or uniform but consists of two clusters, one between 5–25 cm and the other around 45–50 cm, with a gap in between.

Thus, the correct answer is: A. The distribution consists of two clusters and a gap.

Tip: Always examine the shape of a distribution to determine whether it's normal, skewed, or contains clusters. This helps in understanding the underlying data patterns.
