The correct option is C Budding
Yeasts are eukaryotic micro-organisms. The most common mode of vegetative growth in yeast is asexual reproduction by budding. Here, a small bud or daughter cell, is formed on the parent cell. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell. The bud continues to grow until it separates from the parent cell, forming a new cell.
Thus, the correct answer is option (C), 'Budding'.
