Step 1: Concept Clarification:
Intellectual Disability, previously termed Mental Retardation, is categorized by severity based on adaptive functioning across conceptual, social, and practical areas. These classifications indicate the extent of support an individual needs. A "higher level of dysfunctioning" signifies a more severe disability and an increased requirement for support.
Step 2: Detailed Breakdown:
The objective is to order the levels of intellectual disability from the highest level of dysfunctioning to the lowest. This means beginning with the most severe and concluding with the least severe.
- Profound Intellectual Disability (D): This represents the highest degree of dysfunctioning. Individuals at this level require comprehensive, pervasive support for all daily life activities.
- Severe Intellectual Disability (C): Positioned as the second-highest level, individuals here necessitate extensive support for the majority of their daily tasks.
- Moderate Intellectual Disability (B): Individuals in this category require limited support for daily living and occupational tasks.
- Mild Intellectual Disability (A): This is the lowest level of dysfunctioning. Individuals often achieve independence with minimal support.
Consequently, the accurate sequence from the highest to the lowest level of dysfunctioning is Profound, Severe, Moderate, and Mild, corresponding to the order (D), (C), (B), (A).
Step 3: Conclusion:
The ordered sequence from higher to lower levels of dysfunctioning is (D), (C), (B), (A). This selection corresponds to option (4).
