Which Statement Best Expresses the Major Difference Between Mitosis and Meiosis

Which statement best expresses the major difference between mitosis and meiosis?

A) Mitosis is cell division in animals;meiosis is cell division in humans.
B) Mitosis is the process by which a single cell with X number of chromosomes divides into two cells,each with the same number of chromosomes;meiosis is the process by which a single cell with X number of chromosomes goes through two stages of division,producing four new cells each with X/2 (half the original number) of chromosomes.
C) Mitosis is the process by which chromosomes are divided;meiosis is the process by which DNA is divided.
D) Mitosis is the process by which cells divide into four different sets of genetic information (called codons) ;meiosis is the process by which cells are joined together and multiplied to create growth and development.
E) Mitosis and meiosis are both types of cell division in which a single cell with X number of chromosomes divides into two cells,each with one half of the original chromosomes;mitosis is associated with the creation of sex cells that determine the sex of the offspring,and meiosis is associated with cell growth and development.
