The chromosomes in meiocytes of fruit fly are:

8

The correct answer is Option (4) → 8

In diploid organisms, specialised cells called meiocytes (gamete mother cell) undergo meiosis. At the end of meiosis, only one set of chromosomes gets incorporated into each gamete.

Fruit flies, or Drosophila melanogaster,  have a diploid chromosome number of 8. In their meiocytes (diploid cells undergoing meiosis), there are 8 chromosomes.
