• A. Completely differ from prokaryotes
• B. Resemble eukaryotes in all respects
• C. It has novel features absent in prokaryotes and eukaryotes
• D. Completely differ from prokaryotes and eukaryotes

Answer 1

The correct option is C It has novel features absent in prokaryotes and eukaryotes

Archaea are the organisms that have similarities with both prokaryotes and eukaryotes. Mostly they are similar to eukaryotes in some respects but not all. These organisms have a unique evolutionary history. Hence they are kept in a separate group. They also have special features like living in harsh environments like in acidic environments, salty waters and salty areas. They also release certain gases which are not released by organisms of other groups.

So, the correct answer is 'It has novel features absent in prokaryotes and eukaryotes'.
