# All of the following are the features of dysplasia EXCEPT: 

A. Enlarged nuclei and cells

B. Increased nuclear to cytoplasmic ratio

C. Hypochromatic nuclei

D. Pleomorphic nuclei and cells

The correct answer is C. Hypochromatic nuclei.

Explanation: Dysplasia is characterized by abnormal cellular changes, including enlarged nuclei and cells, increased nuclear to cytoplasmic ratio, and pleomorphic nuclei and cells (variation in size and shape). These are all hallmark features of dysplasia. However, hypochromatic nuclei (nuclei with reduced staining, appearing pale) are not typically associated with dysplasia. Instead, dysplastic cells often have hyperchromatic nuclei (darkly staining due to increased DNA content), which is a key feature of the condition.
