Answer: (B)

Verified step by step guidance

1. Understand that a histogram is a graphical representation of data distribution, where the horizontal axis is divided into intervals or bins.
2. Recognize that each bar in a histogram corresponds to one of these intervals or bins, not to individual data points or the mean of the data set.
3. Know that the height of each bar represents the frequency or percentage of data values that fall within that specific interval or bin.
4. Distinguish this from a cumulative histogram, where bars might represent cumulative totals, which is not the case here.
5. Therefore, the height of each bar in a standard histogram reflects the percentage of data values within a specific interval or bin on the horizontal axis.
