The correct options are Access rights assigned by resource owners and Individual user accounts.

Access rights assigned by resource owners is the defining feature of discretionary access control because owners of resources grant and revoke permissions at their discretion. Individual user accounts are required so that owners can assign rights to specific identities and so that access decisions and accountability can be enforced for each user.

Service accounts is incorrect because special or automated accounts are not a fundamental requirement of the DAC model. They may exist in an environment that uses DAC but they are not required to establish the model.

Static data classification labels is incorrect because fixed labels are characteristic of mandatory access control where labels and clearances determine access. DAC relies on owner assigned permissions rather than on data sensitivity labels.
