Which of the following statement is true about one-off contract?

A one-off contract is used for a single, non-recurring transaction. This contractual form is highly flexible and is not restricted by the category of the procurement. It can be effectively used for acquiring tangible goods (e.g., a specific piece of machinery), intangible services (e.g., a single consultancy engagement), or specific works (e.g., a minor construction project). The defining characteristic of a one-off contract is its non-repetitive nature, rather than the value, risk, or type of item being procured.

A. A one-off contract covers a single transaction, providing minimal to no opportunity for the supplier to implement quality improvements during its performance.
C. Ad-hoc purchasing is a term used to describe unplanned, non-recurring purchases, which is the very definition of a one-off purchase.
D. One-off contracts are not limited to low-value items; they can be used for high-value, high-risk capital acquisitions like major equipment or construction projects.
