What does n mean tor a scrum Team to be cross-function at?

According to the Scrum Guide, a Scrum Team is cross-functional if it includes skilled individuals who together have all the skills necessary to create value each Sprint. This means that the Developers can work on any aspect of the product without depending on others outside the team. The other options are not valid descriptions of cross-functionality, as they either imply that the Developers work in silos or rely on external people (such as business analysts, architects, testers, or separate teams).
