It Is cycas besides paddy fields it also found in vegetative part of cycas ..And being a cyanobacteria it acts as a symbiont and readily perform activity of nitrogen fixation so cycad is more correct answer.

Why not alnus...
In alnus also frankia is present which is also prokaryotic autotrophic nitrogen fixing symbiont

Well the answer should be cycas ...as BGA in it is prokaryotic and autotrophic whereas frankia is dependent on plant for its nutrition when it is in symbiotic relationship with alnus
