The narrow band at "Y" is located on a part of the schedule where activities have been delayed or slowed down.

Such delays typically indicate resource limitations (e.g., insufficient manpower or equipment).

Resource limitations are common in network diagrams to explain such periods.

 Cross-Verification:

Option B: Incorrect. No evidence of rework exists.

Option C: Incorrect. Activity inactivity does not fit the context.

Option D: Incorrect. Sufficient information is provided.

Option A: Correct. Resource limitation fits the observed diagram behavior.
