The answer is the last one: one.

Explanation for each option:

  • Four: This is incorrect. Human gametes do not contain four sex chromosomes. Each gamete contains only one sex chromosome.

  • Three: This is incorrect. Human gametes do not contain three sex chromosomes. Each gamete contains only one sex chromosome.

  • Two: This is incorrect. Human gametes do not contain two sex chromosomes. Each gamete contains only one sex chromosome.

  • One: This is correct. Human gametes, which are sperm and egg cells, each contain one sex chromosome. In humans, the sex chromosomes are X and Y. A sperm cell can carry either an X or a Y chromosome, while an egg cell always carries an X chromosome.
