Answer: C. Metaphase of mitosis.

Explanation :

  • A karyotype of a person reveals the number and the structure of the chromosomes present in his cell.
  • For making a karyotype a somatic cell is chosen which is arrested in the metaphase stage of mitosis.
  • The metaphase stage of mitosis is chosen because at this stage:

A) A complete set of chromosomes is present (cell is diploid).

B) The chromosomes are most condensed at this stage.

  • Due to these reasons, the metaphase stage is selected to prepare a karyotype.
