Detailed Solution & Explanation
A histogram is a graphical tool representing the frequency distribution of continuous data. Using a histogram, we can graphically estimate the mode (via the tallest rectangle and diagonal lines) and the median (by finding the line that divides the total area of the histogram into two equal parts). The arithmetic mean can also be approximated by calculating the weighted average of the class midpoints. However, standard deviation is a measure of dispersion that quantifies the spread of individual observations about their mean. Since grouping data into class intervals in a histogram results in the loss of individual observations, we cannot compute or approximate the standard deviation directly from it. Hence, **Option B** is the correct answer.
