Which one of the following is a correct definition of a supplier category?

Strategic suppliers are those with significant partnering relationships involving senior managers, not merely suppliers of operational products or services as stated in this option.

While Tactical does involve commercial activity and business interaction, the description given does not represent the complete or uniquely distinguishing definition of Tactical as used in ITIL Supplier Management, making it an imprecise pairing.

In ITIL Supplier Management, the Operational category applies to suppliers providing low value and/or readily available products and services. These relationships require minimal strategic engagement and are managed through routine, transactional processes. The Operational tier sits below Tactical and Strategic in terms of management complexity and business impact.

Significant partnering relationships involving senior managers describes the Strategic category, not Commodity, which refers to standard, easily substituted, low-value goods and services.
