You should always use your "library voice" when talking in cubicles
A
Correct answer
Explanation
Using a 'library voice' when talking in cubicles is essential workplace etiquette because it minimizes distractions and helps maintain a professional environment. Cubicle walls don't block sound, so quiet voices are necessary for colleagues to concentrate and work effectively. This courtesy is especially important in open-plan offices where noise carries easily and can disrupt multiple people's work.
