C.
D.

Answer

To solve the question of selecting the incorrect match, we will analyze each option provided in the video transcript step by step.

### Step 1: Analyze Lamp Brush Chromosome
- **Definition**: Lamp Brush Chromosomes are found in oocytes (egg cells) of certain species, particularly amphibians and birds.
- **Stage**: They are arrested in prophase I of meiosis, specifically during the diplotene stage.
- **Conclusion**: This match is correct.

### Step 2: Analyze Polytine Chromosome
- **Definition**: Polytine Chromosomes are characterized by multiple rounds of DNA replication without cell division, leading to large chromosomes.
- **Location**: They are typically found in the salivary glands of certain insects.
- **Conclusion**: This match is also correct.

### Step 3: Analyze L-shaped Chromosome
- **Definition**: The term "L-shaped chromosome" is not a standard term in genetics. Chromosomes can take various shapes during different stages of cell division, but "L-shaped" is not commonly recognized.
- **Conclusion**: This match is likely incorrect, as there is no well-defined association of L-shaped chromosomes with a specific biological context.

### Final Conclusion
Based on the analysis, the incorrect match is the one associated with the L-shaped Chromosome, as it does not correspond to a recognized category or specific biological context in genetics.
