Verified step by step guidance

Understand the structure of an antibody: Antibodies are Y-shaped proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses. Each antibody has a unique region known as the antigen-binding site.

Learn about the antigen-binding site: The antigen-binding site is located at the tips of the 'Y' structure of the antibody. This site is highly specific to a particular antigen, meaning it can bind to only one specific type of antigen.

Explore the concept of specificity: The specificity of an antibody is due to the unique shape and chemical properties of its antigen-binding site, which matches the shape and properties of a specific antigen. This is similar to a lock and key mechanism.

Consider the options given: Evaluate the options based on the specificity of antibodies. Since antibodies are specific to one type of antigen, they cannot bind to multiple types simultaneously or different types.

Conclude with the correct understanding: Based on the specificity of antibodies, the correct answer is that a single antibody can bind to one specific type of antigen.
