Which option allows employees to select from all SHOP plans available at a single metal level tier?

The correct choice enables employees to choose from a complete range of SHOP plans at a specified metal level tier, providing maximum flexibility and choice. This means that if an employer chooses to offer a single metal tier, employees can explore and select any available plan within that tier. This option encourages healthier benefits decisions, as employees have the freedom to select plans that best meet their individual healthcare needs and preferences while remaining consistent with the employer's stipulated metal level.

In contrast, other choices limit employees' options either by requiring them to accept a single plan for all or by restricting them to options offered by only one insurance company, thus reducing their ability to tailor their healthcare choices to their personal circumstances. Additionally, the option that suggests enrolling in plans across all metal tiers would not align with the intended focus on a single tier, making it less relevant to the question.
