What is a bar graph? What is a Pareto chart?What is a bar graph?O A. A bar graph represents the frequencies of values either from left-to-right or right-to-left. The different segments of the bar are used to indicate the different frequencies of each category.O B. A bar graph is a horizontal or vertical representation of the frequency or relative frequency of the categories. The height of each rectangle represents the category's frequency or relative frequency.O C. A bar graph is a circular graph that uses bars to divide it into segments corresponding to each category. The segments are proportional to the frequency of its category.
