Answer:
D. Immune response
Explanation:
An immune response is defined as any reaction that occurs within a host when its body recognizes and defends itself against pathogenic microorganisms (e.g., viruses, bacteria, protists, etc) and/or chemical compounds that look to be foreign and harmful to the body. When the number of detected pathogenic microorganisms increases, the immune system in the host responds by producing cells that attack them or by producing proteins (i.e., antibodies) that destroy the harmful substances. A substance capable of triggering an immune response is known as an antigen (e.g., a structural protein of a pathogenic virus). There are two distinct types of immune responses: 1-innate immune responses, where the body mounts a response immediately without requiring a previous contact with the harmful antigen and does not retain a memory of previous responses; and 2- adaptive immune responses that only occur after exposure to an antigen, these responses are slower but they are specific and produce immunological memory.

CPR: CPR is an emergency procedure for a person whose heart has stopped or is no longer breathing. When someone's blood flow or breathing stops, seconds count. Permanent brain damage or even death can occur. If you know how to perform CPR or Cardiopulmonary resuscitation, you could save someone's life. CPR can maintain circulation, blood flow, and breathing until medical help arrives. Even if you haven't had CPR training, you can do hands-only CPR for a teen or an adult whose heart has stopped beating. Hands-only CPR is not recommended for children. Hands-only CPR uses chest compressions to keep blood circulating until medical help has arrived. If you <em>have</em> had training, you can use chest compressions, clearing the airway, and do rescue breathing. Rescue breathing helps get oxygen to the lungs for a person who has stopped breathing. To keep your skills in good form, you should repeat the training every two years which is highly recommended.
AED: An A<em>utomated External Defibrillator</em> (AED) is a medical device designed to analyze the heart rhythm and deliver an electric shock to one to restore the heart rhythm/beat back to normal. Uncoordinated heart rhythm is called Ventricular fibrillation. It's often responsible for sudden cardiac arrest, or sudden heartbeat stopping. Sudden cardiac arrests occur when ventricular fibrillation takes place or when the heart stops beating altogether. Without medical attention, the victim may collapse, lose consciousness, becomes unresponsive, and die. Many victims of cardiac arrest have no history of heart disease and are stricken without a warning. Chances of survival from sudden cardiac death diminish by 7 to 10% for each minute without immediate CPR. After 10 minutes, resuscitation rarely succeeds, and the patient or victim... dies.
