The correct option is A All of the above
Introduction to vegetative reproduction
Vegetative reproduction is the process of producing new organisms from the vegetative parts of the parental body.
It does not involve the participation of sex organs.
Fragmentation
When the mycelium of a fungus is separated into pieces or fragments and each of those fragments forms a new mycelium, the process is called fragmentation. For example, moulds.
Budding
Budding occurs most commonly in Yeast. It also occurs in some filamentous fungi.
In this process, a bud forms on the outer surface of yeast cells or hyphae of filamentous fungi.
This bud grows at the surface of the parental body till its complete maturation.
When fully matured, the bud is detached from the parent body and the bud develops into new hyphae or cells.
Fission
Fission occurs commonly in unicellular fungi like Yeast.
