Solution

The correct option is B Casuarina equisetifolia
Plants cannot directly absorb atmospheric nitrogen. Nitrogen fixation is a process of conversion of inert atmospheric nitrogen into utilizable compounds of nitrogen, like nitrates, nitrite and ammonia.
Important symbiotic nitrogen-fixing bacteria are rod-shaped Rhizobium in root nodules and Aero rhizobium in stem nodules. Filamentous Frankia occurs in root nodules of Casuarina and Alnus (or Alder).
So, the correct answer is 'Casuarina equisetifolia'
