In humans:

Phase of Mitosis No. of Chromosomes No.of Chromatids

Prophase                                46 92

Metaphase                                   46     92

Anaphase                                   92      92

Telophase                                 92        92

The parent cell divides into two daughter cells during cell division. The stage of the cell cycle known as mitosis is when the parent cell's replicated chromosomes are divided into two nuclei, each of which later acts as the nucleus for the daughter cells.

The S phase, during which the chromosome is duplicated, comes before mitosis. The following phases make up the mitotic process:

Prophase: The chromosomes pair up with their respective copies and condense into a "X" shape. Additionally, there are twice as many chromatids as there are chromosomes because each chromosome has two identical chromatids.

In the metaphase, spindle fibres cling to each sister chromatid and the chromosomes line up end to end along the equatorial plate (cell centre).

Option 1 is the correct answer.
