Answer :
Answer:
The correct answer is C)Opening the mail and recording entries in the sales journal.
Explanation:
It is the correct answer because both activities can be done sitting on the desk, using the same computer. All the other answers refer to activity pairs that would require physical activity, and this would reduce efficiency. For example, making journal records and delivering inventory are extremely disjointed activities, it is like being an accountant and a delivery person at the same job.
