Answer:
The second option is the right answer.
Explanation:
Line graphs show trends or changes over time by displaying a series of data points connected by straight-line segments, representing the relationship between two sets of information.
Line charts should be used to monitor changes over short or long periods and to assist in predictive data analysis. If they are small, with frequent changes in the series, line charts are more efficient than bar charts to visualize the change over time.
