A box-and-whisker plot shows the distribution of monthly salaries for two departments, Sales and Marketing. If the Sales department's plot has a longer box and shorter whiskers compared to Marketing, what does this suggest about the Sales department's salaries?

A Sales salaries have a larger overall range but are more clustered around the median.
B Sales salaries are more spread out within the middle 50% but have fewer extreme outliers.
C Sales salaries are generally higher than Marketing salaries.
D Sales salaries are less variable overall than Marketing salaries.

✓ Correct Answer: Option B

A longer box indicates a larger interquartile range (middle 50% is more spread out). Shorter whiskers suggest fewer extreme values or outliers. Option B accurately describes this interpretation.
