Final answer:
In a Discretionary Access Control (DAC) policy scenario, tasks such as viewing, editing, or destroying information can only be performed by subjects explicitly granted access by the owner of the information.
Step-by-step explanation:
In a Discretionary Access Control (DAC) policy scenario, only a subject that has been granted access to the information can perform tasks such as viewing, editing, printing, and sharing the information. The 'subject' in this context is typically a user, program, or process that requests access to an 'object' (data, file, system resource). In DAC systems, the owner of the object has the discretion to grant access rights to other subjects, which can include permissions to read, write, or execute the object.
In situations involving research data, the subject granted access may also decide to destroy the information upon the completion of the project to prevent its use in ways that were not originally intended, thereby upholding the ownership rights and intended use of the final product and research data.
