Answer:
Line graph and Bar graph
Step-by-step explanation:
Since Line Graph is used to visualize the data that change over time, So Line Graph can use for representation.
Also, since it is a categorical data, so Bar graph is also the best representation for showing how the population of a country changes each month.
Thus, Option A and D is correct.
Further, Line Graph is used to visualize the data that is change over time. Here each information is connected with others.
Scatter Plot is used to visualize the two-dimension graph that uses the point to show the values obtained by both the variables.
Circle graph also known as pie chart used to visualize the data proportionally. Here the arc of the circle is used to represent only the proportion of all the data.
Bar graphs are made up of columns with different labels of categorical data of different heights shows the size of the group of different labels.
