Correct answer: D). Budding
One of the common methods of reproduction in yeast is budding in which the daughter cell arises as a result of an outgrowth of the parent cell. In budding, a clone of offspring is produced that is attached to the parent cell, and when it is mature enough it detaches itself from the parent cell.
Sometimes yeast also participates in sexual reproduction because it is necessary for the genetic variation in the population. At the time of environmentally stress condition, they undergo meiosis and form haploid spores that are released when conditions are normal.
Hence, the correct answer would be option D.
