B. Row x describes meiosis and row y describes mitosis
Explanation:
Mitosis is the process in which a cell divides to yield two daughter cells with same number of chromosomes as the parent cell. The process takes place in the somatic cells or the body cells. For example, a cell with 14 chromosomes divides to produce two cells with 14 chromosomes.
Meiosis on the other hand is the process in which a cell divides into four daughter cells that have half the number of chromosomes as the parent cell. The process takes place in the germ line cells where gametes are produced. For example a cell undergoes meiotic division to produce four cells each with 7 chromosomes.
