C Correct answer
Explanation

On Linux systems, the dynamic linker looks at a cache (/etc/ld.so.cache) to find shared libraries. To add a non-standard path, you must add the directory to /etc/ld.so.conf (or a file in /etc/ld.so.conf.d/) and then run 'ldconfig' to rebuild the cache so the system recognizes the new libraries.
