Which of the following was introduced for 16-year-olds as part of David Cameron's multiculturalism initiative?

The national citizenship service was introduced for 16-year-olds as part of David Cameron's multiculturalism initiative to promote social integration and encourage young people to engage in their communities. The program focuses on fostering a sense of belonging and civic responsibility among participants, allowing them to take part in community projects and experiential learning. This initiative was aimed at bringing together young people from diverse backgrounds to work collaboratively, thereby enhancing social cohesion and mutual understanding.

While other options may sound plausible, they do not accurately reflect initiatives associated specifically with Cameron's agenda in relation to multiculturalism for that age group. The national citizenship service specifically encapsulates the intent of empowering youth through active citizenship, making it the correct choice in this context.
