Which of the following commands will output a list of all of the file names, under your home directory and all subdirectories, which have file names ending with .pdf?

search is not a standard Linux command for finding files by name in a directory tree.

ls does not have a -name option; -R lists recursively but ls cannot filter by filename pattern the way find does.

find /home/*.pdf incorrectly uses shell glob expansion in the path argument instead of the -name predicate, and would not recursively search subdirectories under the home directory.

find ~ -name '*.pdf' starts the search at the user's home directory (~), recursively traverses all subdirectories by default, and uses -name '*.pdf' to match only files whose names end with .pdf, producing the desired output.
