Correct answer
B. B-lymphocytes and T-lymphocytes
Step-by-step solution
Acquired immunity is characterized by being pathogen specific, meaning that it is specific to a particular pathogen encountered by the body. The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes. B-lymphocytes produce an army of proteins in response to pathogens in our blood to fight them. These proteins are called antibodies..An antibody is represented as H₂L₂, with two small peptide chains called lig
