A project manager is reviewing a scatter plot showing 150 employees' 'Years of Experience' (X-axis) versus their 'Average Task Completion Time' (Y-axis, in minutes) for a specific complex task. Employees from different teams (Alpha, Beta, Gamma) are represented by different colored points. The plot shows that Team Alpha's points are clustered in the bottom-left quadrant (low experience, low completion time), Team Beta's points are spread across the middle with a slight upward trend, and Team Gamma's points are predominantly in the top-right quadrant (high experience, high completion time) with significant variability. Which statement is best supported by this data?

A Team Alpha members are generally less experienced but highly efficient on this task.
B Team Beta's task completion time significantly improves with increased experience.
C Team Gamma consists of the most experienced employees, who are also the fastest task completers.
D There is a strong negative correlation between experience and task completion time across all teams.

✓ Correct Answer: Option A

Team Alpha's clustering in the bottom-left quadrant indicates both low experience and low completion time, implying high efficiency despite less experience. The other options are contradicted by the description of the plot.
