According to the theory of plate tectonics, how do two plates interact to form coastal volcanic ranges?
a. a continental plate collides with another continental plate at a convergent boundary.
b. an oceanic plate sinks beneath another oceanic plate at a convergent boundary.
c. an oceanic plate sinks beneath a continental plate at a convergent boundary.
d. a continental plate slides along an oceanic plate at a convergent boundary.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

Where is the rest of the question

This is the most closely resembles the model.
