Reproduction in yeast occurs through which of the following methods?

Yeast is a single-celled microorganism. It commonly reproduces by budding. Budding is a method of asexual reproduction. 

During budding, small outgrowths called buds appear on the body of parent yeast. The nucleus divides and one-half migrates into the bud. The bud grows and matures remaining attached to the parent cell. It then detaches itself from the parent cell.
