The correct answer is (a) Bar diagram.
A bar diagram is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally.
A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been cut into slices, there are variations on the way it can be presented.
A cylinder is a three-dimensional shape with two parallel circular bases and a curved surface connecting them. The bases are congruent and the curved surface is a cylinder’s lateral surface.
A graph is a visual representation of data. It can be used to show the relationship between two or more variables, or to compare different sets of data. Graphs can be made in many different ways, but they all have one thing in common: they use lines, shapes, or symbols to represent data.
In conclusion, a bar diagram is a one-dimensional figure because it has only length and no width or height. A pie chart, cylinder, and graph are all three-dimensional figures because they have length, width, and height.
