What is the distribution of X? X ~ N(,)

The correct option is line graph

Step-by-step explanation:

Given some graph names

we have to choose the graph which show trends over the time.

As we know the pie chart and bar graph works on data and gives the constant value implies cannot show trends over time.

The circle graph also not work with increment of time as it goes around the same point with same distance from centre. Hence, this graph also not  show trends over time.

The line graph also called line chart, it is a type of chart used to visualize the value of something over time.

For example, a finance department may plot change in the amount of cash the company has on hand over time. The line graph consists of a horizontal x-axis and a vertical y-axis.

Hence, the correct option is line graph
