Verified step by step guidance

Understand the concept of an immune complex: An immune complex is a combination of an antigen and an antibody. This complex forms when antibodies bind to specific antigens, which are foreign substances that trigger an immune response.

Identify the components involved in the formation of an immune complex: The key components are antibodies, which are proteins produced by B cells, and antigens, which are molecules capable of inducing an immune response.

Differentiate between the options provided: Analyze each option to determine which one correctly describes the components of an immune complex.

Option 1: T cells and B cells - These are types of lymphocytes involved in the immune response, but they do not form immune complexes.

Option 2: Antibodies and antigens - This is the correct pair that forms immune complexes, as antibodies bind to antigens to neutralize or mark them for destruction.
