Please help me with this question.

That's not a multiple choice question

Which of the following does net apply to XCOPY deployment?

1) The appropriate version of the .NET framework must be installed.
2) All application components must be in the application directory, or a subdirectory.
3) Shared components can be installed as part of the XCOPY.
4) XCOPY deployment to a non-empty target directory may have unintended side-effects
