The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.

Explanation:
B. Muscle cell, also known as myocytes, have more abundant mitochondria than the other cells listed. This is primarily due to the fact that sustained muscular contractions require massive amounts of cellular energy, transported throughout the cell within the phosphate bonds of Adenosine Tri-Phosphate (ATP) molecules. Mitochondria are the cells' organelles that produce ATP, giving them the nickname "energy powerhouses of the cell."
