A user was granted Reader role on a resource group but still cannot access a specific resource inside it. What is the most likely reason?
A. Role assignments at the resource group level do not apply to child resources, so the user will never inherit those permissions.
B. A deny assignment or a more restrictive role at the resource level is preventing the inherited Reader permissions from applying to that specific resource.
C. The Reader role only applies to management group scope and not to resource groups or individual resources.
D. Azure RBAC evaluates only the highest privilege assignment, so a Reader assignment is ignored if any other assignment exists at any scope.
A deny assignment or a narrower role at resource scope can block inherited permissions; inheritance normally applies but can be overridden by denies or explicit assignments.
