Pictorial representation of data is called:A. Bar graph B. HistogramC. Pictograph D. None of these

The correct answer is C. Pictograph.

Explanation:

A pictograph is a type of graph that uses pictures or symbols to represent data. In a pictograph, each symbol or image represents a certain quantity of items or values. It provides a visual way of understanding the data by using pictures instead of numbers or bars.

Now let's look at the other options:

A. Bar graph: This is a type of graph that uses rectangular bars (either vertical or horizontal) to represent data. It does not use pictures or symbols but uses bars to show the frequency or amount of data.

B. Histogram: This is similar to a bar graph but is specifically used for representing the frequency distribution of a set of continuous data. It uses bars but does not use pictures or symbols.

D. None of these: This is incorrect because a pictograph is the correct answer.

So, the correct option is C. Pictograph.
