B Correct answer
Explanation

The 'chmod' (change mode) command modifies file permissions in Unix. Option A 'Changemode' is fictional. Option C 'chper' doesn't exist. Option D incorrectly claims both exist. Option B correctly identifies 'chmod' as the command for permission management (read/write/execute for user/group/others).
