Explanation
The mode is the value that appears most frequently in a dataset, making it the correct statistic to identify the most popular (most common) shirt size. Shirt sizes are categorical (nominal) data - small, medium, large - and cannot be meaningfully averaged or ranked numerically. Mean (B) requires numerical data and would be nonsensical for categories. Median (D) requires ordered, continuous data to find the middle value. Minimum (C) would only identify the smallest size category, not the most popular one. Mode is the only measure of central tendency applicable to nominal/categorical data.
