Answer:
d. budding
Step-by-step explanation:
Budding is a type of asexual reproduction, as are binary division, multiple division, vegetative propagation, and fragmentation. This type of reproduction is observed in some species of animals and plants.
In budding, as the name suggests, sprouts appear on the surface of the organism. These shoots will give rise to a new individual, which may grow on the organism that originated it, forming the colonies, or be released into the environment.
This type of reproduction is common in several plant species, occurring more frequently in angiosperms, and also in some animal species, especially in the cnidarian and porifer group.
