Which of the following benefits is offered at all membership levels?

The Individual Vision Plans (VSP) are offered at all membership levels, making this option the correct answer. This type of benefit ensures that all members, regardless of the specific tier or level of their membership, have access to vision care services, which can include eye exams, discounted eyewear, and other related services.

Providing a standard health benefit like vision care across all membership levels promotes inclusivity and ensures that every member can maintain their eye health, regardless of their financial commitment to the organization. The availability of such an essential service is crucial as it addresses a common health need.

The other options vary in terms of membership eligibility. Some benefits may be tiered, meaning they're only available to higher-level members or those who meet specific criteria, thus limiting access for all members.
