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

Strategic suppliers are defined for significant partnering relationships involving senior managers, not for suppliers of generic operational products or services.

While 'significant commercial activity and business interaction' does describe the Tactical category, this option is a distractor - the question asks which definition is correct, and C provides the precise definition of Operational.

In ITIL Supplier Management, the Operational category is defined for suppliers who provide low value and/or readily available products and services that require minimal management overhead. This distinguishes them from higher-tier relationships that demand greater business engagement or executive involvement.

Commodity is for suppliers of routine operational products or services such as utilities, not for significant partnering relationships involving senior managers, which defines the Strategic category.
