This answer is based on the TOGAF Series Guide: Value Streams 2, which states that “A guiding principle when creating value streams is to avoid going down to operational levels of detail. The purpose of a value stream is to provide a high-level view of how value is created and delivered by an enterprise.” Going down to operational levels of detail can make the value stream too complex and difficult to understand and communicate. It can also obscure the strategic focus and direction of the value stream. The other options are not correct, as they are not guiding principles when creating value streams.
