All are levels of prevention except–

Correct option is D

Sol. In public health, there are three main levels of prevention:
1. Primary prevention (e.g., health promotion, specific protection),
2. Secondary prevention (e.g., early diagnosis and prompt treatment), and
3. Tertiary prevention (e.g., rehabilitation and disability limitation). All three listed options — health promotion, early diagnosis, and rehabilitation — fall under one of these categories. Hence, none of these is excluded from the levels of prevention.
Explanation of each option:
· (a) Health Promotion – Correctly included. It is a part of primary prevention, focusing on education, lifestyle changes, and environmental improvement.
· (b) Early diagnosis – Correctly included. It falls under secondary prevention, which aims to detect diseases in early stages for effective treatment.
· (c) Rehabilitation – Correctly included. It is part of tertiary prevention, helping patients recover and reduce the impact of long-term disease or disability.
· (d) None of these – Correct. Since all options a, b, and c are genuine levels of prevention, the correct answer is that none of them are exceptions.
