SuM4All aims to enhance which of the following?

SuM4All focuses on addressing transport and mobility issues globally. The initiative seeks to facilitate a more sustainable, inclusive, and efficient transport system to improve accessibility and mobility for all. The objective is to make transportation safer, more affordable, and environmentally friendly, ultimately contributing to better social and economic outcomes.

The other options pertain to different global initiatives or goals. Universal access to education is an important area of development that aims to ensure every individual has the opportunity for learning, but it is not the focus of SuM4All. Economic prosperity is a broader term that encompasses various strategies for economic growth but does not specifically relate to transport solutions. Global health initiatives, similar to education and economic growth, are significant but lie outside the scope of SuM4All, which is primarily concerned with transport-related challenges.
