Which of the following environment variables overrides or extends the list of directories holding shared libraries?

LD_LOAD_PATH is not a valid Linux dynamic linker environment variable and is not recognized by ld.so.

LD_LIB_PATH is not a valid environment variable; the correct name includes the word LIBRARY, making this a misnomer.

LD_LIBRARY_PATH is the well-established environment variable recognized by the dynamic linker (ld.so) on Linux systems. When set, the colon-separated list of directories it contains is searched before the default system paths, allowing users to point the linker to custom or updated shared library locations at runtime.

LD_SHARE_PATH does not exist as a recognized dynamic linker environment variable on Linux.

LD_RUN_PATH is a build-time hint used by some linkers to embed an rpath into an executable, not a runtime override for shared library search directories.
