Concept:The correct completion depends on choosing the adverb that most naturally carries the meaning "to a large degree" in the context of a price change.
Explanation:The sentence likely refers to a reduction in price, so the missing word must show a notable amount of change.
"Considerably" means significantly or by a large amount, and it collocates well with a word like "reduced".
"Greatly" is possible, but "considerably" is the more precise choice for describing a quantity or amount.
"Strongly" is normally used for opinions, beliefs, or emotions, not for price changes.
"Most" does not function as an adverb of degree in this pattern.
Thus, the word that best completes the sentence is "considerably".
