Which statement about assigning security access to a parent member is true?

• A. The default access to members dimension for which security is enabled is Write.
• B. When you assign access to a parent member, you can specify that the access will include the descendants.
• C. If a user has Read access to Account member and Write access to the Scenario member of a cell in a data form, the user receives Read access to the cell.
• D. If a user has Read access to Account member and Write access to the Scenario member of a cell in a data form, the user receives Write access to the cell.

Answer: (B)

When you assign security to a parent member, you can choose to apply that access to all of its descendants. This means a single security grant on the parent can automatically propagate down the entire subtree, which makes managing large hierarchies much simpler and ensures consistent permissions across related members.

That’s why this option is the best answer: it directly describes how you can control access across a whole branch of the dimension by applying it to the parent and choosing to include descendants.

The other statements don't fit the question’s focus. One describes a default that isn’t guaranteed (security isn’t automatically Write by default), and the others discuss how cell-level permissions are evaluated across dimensions. Those touches on related concepts, but they are not about propagating a parent’s security to its descendants.
