Explanation

Option A, 'chmod -R 400 /new_directory/', uses two key components: the -R (recursive) flag to apply the permission change to the directory and all files/subdirectories within it, and the octal mode 400 (r--------) which grants read-only permission to the owner with no write or execute bits set. Option B uses 600 (rw-------), which includes write permission - not read-only. Options C and D omit the -R flag, so they only change the top-level directory's permissions and do not affect the contents inside it.
