ANSWER : All of the above are true.

Dimension hierarchies (HIERs):

  1. MBR Names are always unique within their level is True
  2. MBR Names are always unique within their hierarchy  is True
  3. MBR Keys are always unique within their level   is True
  4. MBR Keys are always unique within their hierarchy   is True

All of the above statements about  Dimension hierarchies is TRUE

So, last fift option "all of the above are true" is right answer
