What is the correct definition of antibodies?
Softa [21]

Answer: The answer is  C

Explanation:

 Antibodies or otherwise called Immunoglobulin are special protein that are produced by certain lymphocytes which produces antibodies which can affect the invading bacteria or other foreign  bodies called the antigens  or other toxins in a number of ways . Certain antibodies known as agglutinins make bacteria harmless by causing them to clump together. The lysins dissolve the outer coats of bacteria, the antitoxin neutralize the toxin of bacteria  while precipitins precipitate the toxin as insoluble and therefore , convert them to a harmless compound. Antibodies are always produced by the immune system.
