B Correct answer
Explanation

The 'du' (disk usage) command summarizes disk usage by directory, showing kilobytes used by each subdirectory. Option A incorrectly denies du exists. Option C misidentifies it as a user command (that's 'who' or 'users'). Option D describes 'df' (disk free), not du. Option B correctly describes du's purpose - reporting disk consumption by subdirectory.
