What does the word 'prodigious' signify?

The term 'prodigious' is used to describe something that is remarkably large, impressive, or extraordinary to the point of inspiring awe. This word is often associated with something that stands out due to its size, quantity, or exceptional nature, such as a prodigious talent or a prodigious amount of effort. Its connotation carries a sense of wonder, suggesting that the object or phenomenon in question is not only great but also noteworthy and deserving of attention.

In this context, the other options portray meanings that are contrary to the sense of grandeur encapsulated in 'prodigious.' The terms suggest smallness, ordinariness, or mediocrity, which fundamentally differ from the awe-inspiring qualities that define anything described as prodigious. Therefore, the choice that accurately reflects the definition of 'prodigious' as something that strains credulity in its greatness is the one that indicates awe-inspiring magnitude or quality.
