Correct answer: (A) Line chart

Explanation

Variations in time series data are best represented by a line chart.

A line chart plots values against time and reveals trends, rises and falls clearly.

A pie chart shows composition at a single point and cannot display change over time.

A bar chart compares discrete categories rather than tracing a continuous time trend.

A scatter plot displays the relationship between two variables, not movement over time.

Connecting successive time points by a line makes cyclical and seasonal patterns visible.
