Explanation
The correct word to fill in the blank is A: Sight.
The phrase "It was a sight to behold" is a common expression that is used to describe a visually impressive or awe-inspiring experience or scene. "Sight" refers to something that is seen or the act of seeing, and in this context, it is used to convey the idea of a stunning or remarkable spectacle.
Option B, "Site," refers to a location or place, and it is not the correct word to use in this phrase. Option C, "Scenery," refers to the natural features of a landscape or view, and while it is related in meaning to "sight," it is not the correct word to use in this phrase. Option D, "Seen," is the past participle of the verb "see," and it is not the correct word to use in this phrase, as it does not convey the same sense of amazement or wonder.
Therefore, the correct word to fill in the blank in the phrase "It was a _________ to behold" is "sight."
