Which term is defined as antibodies including IgA, IgD, IgE, IgG, and IgM?

Explanation:
Antibodies are immunoglobulins, a family of glycoprotein molecules produced by plasma cells that fight infections. They come in five classes—IgA, IgD, IgE, IgG, and IgM—each with distinct roles in immune defense: IgM is the first responder and activates complement; IgG is the most abundant and provides long-term protection; IgA guards mucosal surfaces; IgE is involved in allergic responses and parasite defense; IgD mainly acts as a B cell receptor. The other terms refer to a disease, a secretion, and a growth, not antibodies.
