Answer:
false
Explanation:
-exec option is not mandatory for the find command.
find will still list out the identified files even in the absence of -exec option.
For example:
find . -name test -print
will print out files with the name 'test' in the current directory. Note that there is no exec option in this example.
Same holds true for find with no additional options at all.
For example:
find .
will list out all files in the current directory.
