Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion
Step-by-step solution
In all the septate fungi except basidiomycetes (dolipore septum), the septa are seldom complete. They are perforated and contain plasmodesmata or small central pores. Septal pores allow protoplasmic continuity between adjacent cells. This is useful for quick translocation of nutrients to all part of the body, mobilisation of reserve materials from older parts to younger parts and from vegetative hyphae to reproductive hyphae.
