A.

Budding

Yeast are unicellular (some are multicellular) eukaryotic micro-organisms belonging to the kingdom fungi. Yeast size can vary greatly depending on the species, typically measuring 3-4 pm in diameter. Most yeasts reproduce asexually by an asymmetric division process called budding. First, it produces a small protuberance on the parent cell that grows to full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell. The bud detaches from the mother's body by forming a constriction at the base. Budding will repeat to form a chain of bud cells. The daughter cell produced during the budding process is generally smaller than the mother cell.
