• D. If both the assertion and reason are false

Answer 1

The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion

Anabaena is found symbiotically associated with the roots of leguminous plants. They inhabit specialized structures formed by the roots called the root nodules and help in N${}_2$ fixation.

Therefore both assertion and reason are true but reason is not the explanation of assertion.

So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'
