Hint: Immunity acquired by infection/vaccination is termed as active immunity. The type of immunity acquired by transfer of antibody/lymphocytes from an immune donor is passive immunity.
Acquired immunity is in contrast to innate immunity. It is stimulated when a pathogen enters the innate immune system and releases a threshold level of antigen and generates signals activating other immune cells.
Complete answer:
The adaptive immune system, likewise alluded to as the acquired immune sytem, is a subsystem of the immune framework that is made out of particular, foundational cells and cycles that takes out microorganisms by forestalling their development. Acquired immunity makes immunological memory after an underlying reaction to a particular microbe, and prompts an enhanced reaction to ensuing experiences with that microorganism. This cycle of acquired immunity is the premise of vaccination. The acquired immunity incorporates both humoral immunity parts and cell-mediated immunity segments. It is profoundly explicit to a specific microorganism. Acquired resistance can likewise give enduring assurance.
Antigens are any substances that evoke the acquired immune response (regardless of whether versatile or maladaptive to the living being). The cells that do the acquired immune response are white blood cells known as lymphocytes. Two fundamental activities—antibody response and cell mediated immune response—are additionally completed by two distinct lymphocytes (B cells and T cells). In counteracting agent reactions, B cells are enacted to discharge antibodies, which are proteins otherwise called immunoglobulins. Antibodies travel through the circulation system and tie to the unfamiliar antigen making it inactive, which doesn't permit the antigen to tie to the host.
As an individual's immune system experiences different antigens, the segments of acquired immunity locate the most ideal approach to assault every antigen and start to build up a memory for that antigen. It is likewise called specific immunity. Acquired immunity sets aside some time to create after starting presentation to another antigen. Lymphocytes are the sort of white blood cells liable for acquired immunity. Acquired immune response starts with antibodies, delivered by B cells or B lymphocytes.
Hence, the correct answer is option (B)
Note: It is also important to understand that acquired immunity is not as good as the innate, however, it is the memory used can lead to faster response to recurrent or subsequent infections. Also, it can be customized by genetic recombination to recognize epitopes and antigenic determinants.
