Which option correctly identifies the three dimensions of disability according to the World Health Organization?

• A. Impairment
• B. Activity limitation
• C. Participation restrictions
• D. All of the above

Answer: (D)

The main idea here is understanding how the WHO’s model views disability in three interconnected parts: impairment, activity limitation, and participation restriction. Impairment refers to problems with body function or structure. Activity limitation means difficulty performing tasks or actions. Participation restriction involves challenges in taking part in life situations, such as work, social activities, or community life. Together, these three dimensions capture the full scope of disability as defined by the WHO’s framework, and recognizing all three is essential. That’s why selecting “All of the above” is the best choice. Contextually, environmental and personal factors can influence how these dimensions manifest, but the trio itself remains the complete set.
