Which of the following best conveys the concept of a 'plethora'?

The term 'plethora' refers to an excessive amount or an abundance of something. When you think of a 'plethora,' it's synonymous with having more than enough or a surplus of items or resources. In this context, the choice of 'surplus' accurately captures that meaning, as it indicates an overabundance or excessive quantity beyond what is needed or expected. Understanding this concept is essential, especially in contexts where resource management or supply levels are discussed, as it emphasizes the contrast between having too much and not enough.
