which of the following kingdom are archaebacteria and nitrogen fixing organisms classified?

Dear student,
Please find below the answer:

The correct option is (4).
Archaebacteria and nitrogen-fixing organisms (bacteria) are classified under Kingdom Monera. Monera is a kingdom which consists of the single-celled organisms like bacteria. These organisms are without a nucleus and hence they are called prokaryotic. 

Hope this clears your doubt.
