Final answer:
The working party is responsible for saluting an officer through a designated individual, often the person in charge. The officer will then return the salute.
Step-by-step explanation:
When an officer approaches a working party, it is traditionally the responsibility of a designated individual within the working party to salute on behalf of the group. This individual is usually the person in charge of the working party, or the highest-ranking non-commissioned officer present. Therefore, the correct answer is the working party. The officer is not required to initiate a salute, though they are expected to return the salute as a matter of courtesy and respect. This protocol helps maintain discipline and order while also allowing the working party to continue their duties with minimal interruption.
