When the body encounters a pathogen for the first time, the initial immune response is low in intensity. However, upon subsequent encounters with the same pathogen, a higher, more intensified immune response occurs, known as the secondary response. This secondary response is characterized by increased speed and effectiveness due to the presence of immunological memory. The memory mechanism allows the immune system to remember and specifically target the pathogen, resulting in a quicker and more targeted defense against the infection or illness.Hence, the correct answer is option 3.
