c is the answer i hope so friend

Answer 2

The purpose of these nodules is a) The nodules contain bacteria which can convert atmospheric nitrogen into ammonia.  

Leguminous plants fix atmospheric nitrogen, through a symbiotic association with bacteria, by converting it into ammonia. Nitrogen is required to produce proteins and nucleic acids and most plants acquire it through nitrogen rich fertilizers.  

Roots of leguminous plants allow the invasion nitrogen fixing bacteria (Rhizobium), these organisms then multiply to form nodules. The mutualism between the two organisms is maintained as the bacteria provides nitrogen and receives shelter, to and from the plant respectively.
