The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Organism**: The question asks about Drosophila melanogaster, which is commonly known as the fruit fly. 2. **Understand Chromosome Composition**: Drosophila melanogaster has a specific number of chromosome pairs. It is important to differentiate between autosomes and sex chromosomes. 3. **Count the Chromosome Pairs**: - Drosophila melanogaster has a total of 4 pairs of chromosomes. - Out of these, 3 pairs are autosomes (non-sex chromosomes). - 1 pair is made up of sex chromosomes (X chromosomes). 4. **Summarize the Findings**: Therefore, Drosophila melanogaster possesses 3 pairs of autosomes and 1 pair of sex chromosomes. 5. **Select the Correct Option**: Based on the analysis, the correct answer is "3 pairs of autosomes plus 1 pair of sex chromosomes." **Final Answer**: Drosophila melanogaster possesses 3 pairs of autosomes plus 1 pair of sex chromosomes. ---
