Answer: D

Explanation:

The user story provided is quite broad and encompasses multiple functionalities, which suggests it is more of an epic than a small, deliverable user story. The INVEST criteria for Agile user stories require that stories be Independent, Negotiable, Valuable, Estimable, Small, and Testable.

In this case:

Independent: This user story seems to have dependencies, as the ability to print the bill, view it in different currencies, and flag items are likely interconnected functionalities.

Negotiable: The user story provides specific solutions rather than outlining the problem to solve, which limits the negotiation on how to implement the solutions.

Valuable: The story does provide value to the hotel guest, which is clear.

Estimable: With the information provided, the development team can likely estimate the effort required.

Small: The story is not small; it covers multiple features that probably cannot be delivered in a single iteration.

Testable: The acceptance criteria are testable, although they are quite detailed and prescriptive.

Reference = The explanation is based on the INVEST criteria as described in Agile methodologies1234. The criteria are used to assess the quality of a user story, ensuring it is well-defined and suitable for Agile development practices. The user story in question does not fully meet the ‘Negotiable’ and ‘Small’ criteria, which is essential for maintaining flexibility and delivering incremental value in Agile projects.
