In standard English usage, which of the following words is the best opposite (antonym) of “Enormous”, which means very large or huge in size or extent?

Introduction / Context:
This vocabulary question asks you to identify the antonym of the word “Enormous”. Knowing common adjective pairs such as big and small, huge and tiny, or enormous and minute is crucial for success in many English language sections. Antonym questions check whether you can accurately reverse the sense of a given word rather than simply recognise similar meanings or approximate associations.

Given Data / Assumptions:
1) The target word is Enormous.2) Options are tiny, large in size, high quantity and to the most extent, plus the possibility that none is correct.3) We use standard dictionary meanings of Enormous and each option.4) The correct answer must be opposite in meaning, not just different.

Concept / Approach:
Enormous is an adjective that means very large, huge, gigantic or extremely big. Therefore, an antonym must describe something very small in size or extent. Among the options, look for the one that directly conveys smallness. Phrases that reinforce largeness or intensity cannot be correct. Recognising such direct opposite pairs is often simpler than trying to memorise many synonyms and helps solve these questions quickly.

Step-by-Step Solution:
1) Define Enormous: It means extremely large, huge or of great size.2) Evaluate option tiny. Tiny means very small or minute, which is the direct opposite of very large.3) Evaluate option large in size. This is almost a restatement of Enormous and clearly not an antonym.4) Consider high quantity. This phrase suggests a large amount or number, again reinforcing the idea of bigness rather than opposing it.5) Consider to the most extent. This phrase implies a very high degree or level, which also aligns with the sense of largeness or intensity.6) Since only tiny explicitly expresses a very small size, it is the only true opposite of Enormous in the list.

Verification / Alternative check:
Place Enormous and each option into a simple contrastive sentence. For example, “The elephant is enormous, the mouse is tiny” forms a natural pair. Saying “The elephant is enormous, the mouse is large in size” makes no sense as a contrast. Similarly, phrases involving high quantity or most extent do not produce a clear opposite relation when paired with Enormous. This quick contextual test reinforces tiny as the correct antonym.

Why Other Options Are Wrong:
“large in size” is synonymous or at least very close in meaning to Enormous, not opposite.“high quantity” refers to a big amount, which again is conceptually similar to being enormous in magnitude.“to the most extent” suggests maximum degree, which complements rather than contradicts the idea of being enormous.None of these fails because tiny already provides the exact opposite meaning required.

Common Pitfalls:
Students sometimes misinterpret antonym questions as asking for any word that is simply not a synonym. They may choose a phrase that is only weakly related or not related at all, rather than the most direct opposite. Another mistake is overcomplicating simple adjective pairs, especially under time pressure. Remembering clear everyday relationships, such as enormous tiny, big small, tall short and fast slow, is very helpful in solving such questions quickly and accurately.

Final Answer:
The best antonym of Enormous among the given options is tiny.
