Answer:
B. The status report was delivered by the chief operating officer
Explanation:
All the other options except b, make no difference from the sentence fragment itself. Only option b completely exposes the mind of the writer. The other options are incomplete sentences.
A sentence is incomplete if it lacks the proper subjects, verbs, objects, or if it does not make a complete sense.
Option b describes the action carried out by the chief operating officer, without leaving any detail unrevealed.
