Answer:
The correct answer will be option-B.
Explanation:
Viral polymerases are the enzymes which play an important role in the viral genome transcription and replication.
Retrovirus is the single-stranded RNA viruses which replicate through a DNA intermediate and therefore requires the <em>RNA-dependent DNA polymerase or reverse transcriptase</em>. Reverse transcriptase encodes DNA from the strand of RNA which can be replicated and helps in the reproduction of the virus.
Thus, option- B is the correct answer.

The evaporation process uses the sun radiation or sun’s
thermal energy for vaporization of a water from the land or soil to be water
vapor then in the air. Transpiration on the other hand is the same with evaporation
that involves water molecules to be vaporized into the air but it is located in
the stoma of the plants. It is like evaporation within plants. This is actually
to have homeostasis in plants and still part of the water cycle.
Eukartyotic cells are found as bacteria or archaea. They are usually unicellular organisms. Has no nucleus. Has a very small cell size.
Prokaryotic cells are found in plants and animals. They are multicellular. Has a nucleus. And has a much bigger cell size.
They can have many of the same organelles, but prokaryotic cells are usually more advanced. They are both forms of life. They are both cells.
