Which of the following statements is incorrect?

The question asks to identify the incorrect statement. Let's analyze each option: a)* The beginning of this statement is cut off, but the visible part reads: "...significant public health problem of developed countries whereas malnutrition is a problem of under-developed countries." This statement is generally correct. For example, obesity and related non-communicable diseases are significant public health problems in developed countries, while under-nutrition (malnutrition) is more prevalent in less developed countries. b)* "Certain diseases like cardiovascular diseases and cancers are more common in well developed countries than in the less developed countries mainly because of changes in lifestyle resulting from economic development." This statement is correct. As countries undergo economic development, lifestyle changes (e.g., increased consumption of processed foods, sedentary lifestyles, tobacco use) often lead to a rise in non-communicable diseases (NCDs) such as cardiovascular diseases and cancers. This phenomenon is part of the epidemiological transition. c) "Concern for the health of poor people who are mostly in developing countries, is no longer a central development issue." This statement is incorrect. The health of poor people, especially those in developing countries, remains a central* and critical development issue. Global health initiatives, international aid, and the Sustainable Development Goals (SDGs) all emphasize improving health outcomes for vulnerable populations as fundamental to overall development. Neglecting the health of the poor would severely impede social and economic progress. d)* "Substantially improved health outcomes are a pre-requisite if developing..." The rest of the sentence is cut off, but the visible part implies that improved health outcomes are necessary for development. This is correct. A healthy population is more productive, has higher educational attainment, and contributes more effectively to economic growth and societal well-being. Therefore, the incorrect statement is c. The final answer is c
