Aline graph can show information

a across days only

b. across months only

c. across many years

d. across hours only

select the best answer from the choices provided

Option C

Explanation: In a line graph, you can use the time scale that you want or need, it can be measured in hours or years, meaning that if the graph shows something that is happening quickly, maybe its better to use hours, and if the graph shows something that happens slowly is better to use a bigger measure, like days, weeks or more.

So the right answer is C; a graph can show information across many years (and in between, of course)
