Answer:
B, Paula will improve her work efficiency
Explanation:
Scheduling times to review voicemail messages is a time management and efficiency improvement skill.
This is because Paula has maximum concentration/dedication on/to whatever task Paula is working on without having to interupt her flow by going through voicemail messages intermittently. This dedication/concentration brings about an improved work efficiency in Paula and she can acheive a lot more than when she had no voicemail review schedule.
Cheers.
