Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Future work that hasn't been started.
Why it's wrong here
This is the backlog.
- ✓
Work waiting in an inbox or system that is not explicitly tracked.
Why this is correct
These are the most dangerous queues because they are ignored.
- ✗
Work that has been completed but not yet verified.
Why it's wrong here
This is a standard 'waiting' state, not an invisible queue.

The time spent in planning meetings.
Why it's wrong here
This is an explicit process step.
