Which of the following is one of the public health campaigns?

Change4Life is a well-known public health campaign in the UK that focuses on encouraging healthier lifestyles among families, particularly in the areas of nutrition and physical activity. Launched by Public Health England, its initiatives aim to reduce childhood obesity and promote healthy eating, regular exercise, and greater awareness of food choices. The campaign provides resources, tips, and community support to make healthier lifestyles more accessible and appealing, helping to instill lifelong habits in children and their parents.

The other choices refer to initiatives or concepts that may exist but are not recognized specific national public health campaigns in the same way as Change4Life. Health for All is a broad concept often associated with global health efforts, while Community Health Initiative and Wellness Warriors might represent local or grassroots efforts rather than structured national campaigns.
