Solution

The correct option is B Mostly polyploid
Tapetal nuclei in anthers are polyploid in nature. It is because they are multinucleate in nature and the ploidy level is also manifold. This results in the tapetal layer providing nutrients and regulatory molecules adequately to the developing pollen grain.
So, the correct answer is 'Mostly polyploid'
