Verified step by step guidance

Step 1: Begin by understanding the term 'dysplasia.' Dysplasia refers to the abnormal development or growth of cells, tissues, or organs. It is often associated with changes in size, shape, and organization of cells.

Step 2: Review the provided answer choices to identify the correct definition. The options are: programmed cell death, normal growth, abnormal development, and complete absence.

Step 3: Eliminate incorrect options by comparing them to the definition of dysplasia. For example, 'programmed cell death' refers to apoptosis, which is unrelated to dysplasia. Similarly, 'normal growth' does not describe dysplasia, as dysplasia specifically involves abnormal development.

Step 4: Consider the remaining options. 'Complete absence' refers to agenesis, which is the failure of an organ or tissue to develop entirely. This is distinct from dysplasia, which involves abnormal development rather than absence.

Step 5: Conclude that the correct answer is 'abnormal development,' as it aligns with the definition of dysplasia and is the most accurate choice among the options provided.
