In your database, the current status of a PL/SQL procedure has become INVALID. Which action would fix the problem and make the PL/SQL procedure usable?

Executing ALTER PROCEDURE <name> COMPILE forces Oracle to recompile the stored procedure, resolving any dependency invalidations by re-checking referenced objects and regenerating the compiled p-code; if all dependencies are valid, the procedure status returns to VALID and becomes executable.

Changing the rights model to definer's rights affects which schema's privileges are used at runtime, but does not recompile the procedure or remove the INVALID status caused by a broken dependency.

Switching to invoker's rights similarly changes runtime privilege resolution and has no effect on the compilation error or INVALID status of the stored object.

Granting EXECUTE to PUBLIC allows more users to call the procedure but does not trigger recompilation or resolve the underlying dependency issue that caused the INVALID status.
