Which term refers to antibodies: IgA, IgD, IgE, IgG, IgM?

Explanation:
Antibodies are a type of protein called immunoglobulins. The classes IgA, IgD, IgE, IgG, and IgM are all immunoglobulins, different forms that the immune system uses to recognize and neutralize pathogens. So the correct term for antibodies is immunoglobulins. The other options don’t describe antibodies: rhoncus (or rhonchi) refers to a lung sound, sputum is mucus coughed up from the lungs, and poikilocytosis is a term for variation in red blood cell shapes.
