What does the term 'myriad' refer to?

The term 'myriad' refers to a large indefinite number, conveying the idea of an uncountable or diverse multitude. It originates from the Greek word for ten thousand and has evolved to describe countless or innumerable things in modern usage. When someone uses the word 'myriad,' they are typically emphasizing the vastness and variety of whatever they are discussing, whether it's options, species, or any other items. This understanding aligns perfectly with the chosen answer, which highlights the term's association with abundance rather than a defined or limited quantity.

In contrast, the other choices relate to concepts of restricted or minor amounts, which do not capture the essence of 'myriad.' Thus, the definition that focuses on an expansive or unidentified quantity is the appropriate interpretation of the term.
