An administrator is logged on as an unprivileged user and needs to compile and installed an application from source. Which of the following BEST represents how to complete this task?

Option A is the only choice that includes 'sudo', providing the elevated privileges required when 'make install' writes compiled binaries to system-owned directories such as /usr/local/bin or /usr/lib. Without sudo, an unprivileged user will receive permission denied errors during the install phase. Although best practice places sudo only before 'make install', A is the only option among the choices that supplies any elevated privilege to the process.

Option B applies sudo only to the 'make' compilation step but not to 'make install', which means the final installation to system directories will still fail with a permission denied error.

Option C runs all three steps without any sudo, so 'make install' cannot write to protected system directories and the installation will fail.

Option D is identical to C - the absence of sudo at any point means 'make install' will be denied the permissions needed to place files in system directories.
