B.) A chemical reaction
C.) Matter is surface area increases
D.) Destroyed
When chemical bonds break and new bonds form then the Chemical Reaction takes place. The option B is the correct option.
A chemical reaction is the transformation of one or more chemicals, known as reactants, into one or more new substances, known as products. Breaking and establishing chemical bonds are the processes that change reactants into products.
Chemical reactions are an essential component of technology, society, and life itself. Many tasks that involve chemical reactions include burning fuels, smelting iron, creating glass and pottery, brewing beer, and making wine and cheese.
Thus, the correct option is B. A Chemical reaction.

English Translation:
V: Virus, is a very small organism, which does not have the capacity to reproduce itself. This particular virus reproduces only by invading human cells, it does not affect animals. HIV is a fragile virus that cannot survive outside the body.
I: Immunodeficiency, because the effect of this virus is to create a deficiency in the proper functioning of the body's immune system. It infects and destroys immune cells, called T4, to grow and reproduce. It causes the organism to be defenseless, this situation is used by various infections and cancers to attack the organism and cause its death. These diseases are called "opportunists," because they take advantage of the weakness of the immune system to attack. Over time the virus weakens the person's defenses against the disease, leaving him vulnerable to many infections and forms of cancer that would not develop in healthy people.
H: Human, because the virus can only be contracted by humans. In the animal kingdom there are viruses with similar characteristics in apes and felines. It is believed to come from a specific type of African monkey.
HIV belongs to retroviruses. HIV can only replicate inside the cells, ordering the reproduction to the machinery of the cell. It belongs to the family of retroviruses, which means that it is able to reverse the direction of the information that normally flows from DNA to RNA, but in this case it does it in the opposite direction thanks to the reverse transcriptase, thus introducing its genetic code and through the integrase it "integrates" the code of the infected CD4 cell, which allows it instead of multiplying, what it does is produce new viruses, called virions.
HIV is a lentivirus. HIV belongs to a subset of retroviruses called lentiviruses, or "slow" viruses. The course of infection by these viruses is characterized by a prolonged period between the initial infection and the appearance of severe symptoms. It is known that from the moment of the initial infection it reproduces constantly, mainly in the lymphatic system.
Typhoid fever is a bacterial infection that affects the intestine and occasionally the bloodstream. The germ that causes typhoid is a variety of salmonella, called Salmonella typhi. The disease can be contracted by anyone, but the greatest risk is that of people who visit countries where the disease is common.
