The correct answer is D. sporulation.
Bread mold is a fungus which reproduces asexually by the method called sporulation or spore formation. During sporulation a special hyphae called sporangiophore develops upright from the mycelium. The apical cell of the special hyphae become bulb like structure called sporangia. Within the sporangia a large number of sores are formed by mitosis. On busting of sporangia wall, spores are released into the environment. These spores land on the suitable substratum to start new life cycle.
