In which one of the following options the stages of mitosis have been given in correct sequence ?
(a) Prophase, metaphase, telophase, anaphase
(b) Prophase, metaphase, anaphase, telophase
(c) Anaphase, telophase, prophase, metaphase
(d) Telophase, anaphase, prophase, metaphase

Mitosis is the process of cell division, and is separated into four stages. During prophase, the chromosomes condense and the nuclear envelope dissolves. During metaphase, the chromosomes align at the center of the cell. During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. During telophase, the nuclear envelope begins to re-form around the divided chromatids.

So, correct sequence is: prophase, metaphase, anaphase, telophase

Hence, option (b) is correct.
