The answer is C, they show info about years in the past, present and future, ask your teacher or any website and they can show you a line graph. :)
Answer: 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)
