Answer: d. Cost of organization sustaining activities
Step-by-step explanation:
Organization sustaining activities are those undertakings that have to be made if a company can keep operating. Examples include; property taxes, insurance, information filing with Government agencies and etc.
These activities are therefore not directly linked to the production process as they are not related to a single product and so should not be included in product costs for internal management reports which will be used for decision-making.
