Every Scrum Team should nave:(choose the best answer)

According to the Scrum Guide, every Scrum Team should have the competencies and skills needed to deliver an Increment in a 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 what every Scrum Team should have, as they either imply that the Developers work in silos or rely on external people (such as a lead developer or representatives from different departments).
