Explanation

Common mistakes.

B. Applying sudo to make is generally unnecessary as compilation usually occurs in user-writable directories, while make install without sudo would fail due to permission errors.
C. Running all commands without sudo would cause make install to fail because an unprivileged user lacks the permissions to write to system directories.
D. This option is identical to C, and also lacks the necessary sudo for the make install step.
