What can be inferred if the line graph shows a parallel trend between Product A and Product C's sales?

Step 1: Look at the line graph showing sales for Product A and Product C.
Step 2: Check if the lines for Product A and Product C move in the same direction over time.
Step 3: If both lines go up and down together, this means they have similar sales trends.
Step 4: Understand that similar trends suggest that Product A and Product C might be competing for the same customers.
Step 5: Conclude that if the sales trends are parallel, it indicates competition in the same market.
