The answer is; producing a unique antibody from all other B cells by genomic rearrangement.
An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.

I think it's D because I suppose that 'all its chromosomes' equals diploid
Answer:
Particulates are small particles, roughly one to a few tens of micrometers in size, suspended in the air. They are individually invisible but in large concentrations, they may give a "color" to the atmosphere. The extent to which particulates are present in the atmosphere are an important indicator of air quality.
