• B. Production of plasmodesmata

Answer 1

The correct option is A Formation of callus

The process of joining of a tissue or a small part into the tissues of another plant is called Grafting. The tissue or part inserted is called stock and the plant into which foreign part is inserted is called scion. During this process, a group of cells are formed initially. It is called callus.

So, the correct option is ‘Formation of callus’.
