I believe the correct answer to this question is B.
This is the correct answer because the other options can be eliminated and this choice represents the proper process described in the question. Answer choice A describes photosynthesis, which is not being asked about in the question. Answer choices C and D are either partially false or describe an unmatching process with the question.
I hope this is correct and helps you!

Because of their ability to undergo FREQUENT MUTATIONS, VIRUSES CAN RAPIDLY EVOLVE.
Viruses are one of the microscopic organisms that causes diseases in plants, animals and humans. Diseases cause by virus are usually difficult to treat because of the capacity of viruses to undergo frequent mutations; that is, they change their genetic components in a very rapidly manner, in such a way that, their genetic components are never the same for long. This makes it difficult for scientists to make effective drugs against viruses. Two different viruses can also combine together to form a new and unique type of virus. This is the major reason why diseases such as HIV, do not have a cure yet.
Answer:
metal
Explanation:
Metals have unique characteristics that differ from other substances: they are solid, do not let light (they are opaque) and conduct electricity and heat well, having a special shine called metallic. When heated they are malleable and can be molded into various shapes, from wires to plates and bars. For these reasons, we can say that a malleable and ductile material - or capable of being hammered into different shapes without breaking and being pulled by a wire - is probably a metal.
