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
