What command would rebuild the ld.so.cache file?

A.
ldd

B.
ldconfig

C.
ld.so.cache -rebuild

D.
ld

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.
