The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for a disorder where B-lymphocytes and T-lymphocytes are not formed. These lymphocytes are crucial components of the immune system. 2. **Analyzing the Options**: The options provided are: - AIDS - SCID - Cystic Fibrosis - Muscular Dystrophy 3. **Identifying the Correct Disorder**: - **AIDS (Acquired Immunodeficiency Syndrome)**: Caused by the HIV virus, it weakens the immune system but does not stop the formation of B and T lymphocytes. - **Cystic Fibrosis**: Primarily affects the lungs and digestive system, not directly related to lymphocyte production. - **Muscular Dystrophy**: Affects muscle strength and mass, unrelated to lymphocyte formation. - **SCID (Severe Combined Immunodeficiency Disease)**: This is a genetic disorder characterized by the inhibition of the development of both B and T lymphocytes. 4. **Conclusion**: Based on the analysis, the disorder in which B-lymphocytes and T-lymphocytes are not formed is **SCID**. ### Final Answer: The correct option is **SCID (Severe Combined Immunodeficiency Disease)**. ---
