B) Resistance developed after disease
C) Increased heart beat
D) Infection of AIDS virus

Answer 1

Hint: Immunity is the ability of multicellular living beings to oppose destructive microorganisms. Immunity includes both explicit and vague segments. Antibodies are made by the beneficiary and might be put away for all time because of the actuation of memory cells which perceives a similar antigen in future and demolish them.

Complete answer:
The vague segments go about as hindrances or eliminators of a wide scope of microbes independent of their antigenic make-up. Different segments of the invulnerable framework adjust to each new ailment experienced and can produce microbe explicit immunity.

Active immunity is characterized as immunity against microorganism that might harm the immune system and overall health of an individual. When the body is presented to a novel ailment operator, B cells, a sort of white platelet, make antibodies that help with devastating or killing the ailment specialist. Antibodies are y-formed proteins that are equipped for official locales on poisons or microbes called antigens.

Antibodies are illness explicit, implying that every immune response shields the body from just a single ailment specialist. For example, antibodies delivered when the body identifies the infection that causes mumps won't give any guard against cold or seasonal infections. Active immunity results when introduction to a sickness life form triggers the insusceptible framework to deliver antibodies to that ailment. Presentation to the sick living being can happen through contamination with the real infection (bringing about common immunity), or presentation of a murdered or debilitated type of the malady creature through inoculation (immunization actuated immunity). In any case, if an insusceptible individual comes into contact with that malady later on, their resistant framework will remember it and promptly produce the antibodies expected to battle it. Active immunity is enduring, and at times long lasting.

Therefore, the correct option is ‘B’, resistance developed after disease.

Note: Active immunity is the enlistment of immunity after introduction to an antigen. Active immunity can happen normally when an organism or other antigen is obtained by an individual who has not yet come into contact with the microorganism and has no pre-made antibodies for protection. The safe framework will in the end make antibodies for the organism, however this is a moderate cycle.
