Detailed explanation-1: -Prokaryotes are divided into two kingdoms. These are bacteria (sometimes known as eubacteria) and archaebacteria (or the Archaea).

Detailed explanation-2: -Under the five-kingdom classification given by R.H. Whittaker, prokaryotic organisms are placed in the kingdom Monera. Kingdom Monera has unicellular prokaryotic organisms. They do not have a well-developed nucleus or advanced cell, neither they possess any cell organelles.

Detailed explanation-3: -The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.

Detailed explanation-4: -There are two prokaryotic kingdoms which are Archaea and Eubacteria. This would be consistent with answer choice “D. Archaebacteria".
