The term 'myriad' refers to a large, often indefinite number or variety of something. It is commonly used to describe a vast multitude, highlighting the abundance or wide array of options available. In contexts where the term is used, it conveys the idea of richness and diversity, emphasizing that there is not just a single type or quantity but rather a plethora of possibilities.

In contrast, the other options do not align with the definition of 'myriad.' A lack of quantity would imply a scarcity, which directly contradicts the notion of having many. Describing something as a dramatic event does not pertain to quantity or variety, and a peaceful moment suggests tranquility rather than an extensive assortment. Thus, the choice that encapsulates the essence of 'myriad' is the one that denotes an excessive number or variety.
