What file should be edited to make the system aware of newly added library files?

A.
/etc/modules.conf

B.
/etc/conf.modules

C.
/etc/ld.so.conf

D.
/etc/ld.so.cache

E.
/etc/LD_LIBRARY_PATH.conf

Explanation:
ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf,
and in the trusted directories (/lib and /usr/lib). The cache is used by the run-time linker, ld.so or ld-linux.so. ldconfig checks the header and file names of the
libraries it encounters when determining which versions should have their links updated.
Some files:
/lib/ld.so run-time linker/loader /etc/ld.so.conf File containing a list of colon, space, tab, newline, or comma spearated directories in which to search for libraries. /
etc/ld.so.cache File containing an ordered list of libraries found in the directories specified in /etc/ld.so.conf
