Best Answer Explained in Below-:

In the given sentence, "Each 'furniture' on display in the central mall 'is' on sale for thirty 'percent' off the 'regular price'," the word 'furniture' is not used correctly. The term "furniture" is a collective noun that typically refers to items such as chairs, tables, and sofas collectively. In English grammar, when using the term "each," it should be followed by a singular noun. However, "furniture" is considered a plural term even though it represents a singular concept.

The grammatically correct term for the context of the sentence would be "piece of furniture" or simply "item" to refer to individual items on sale. This error is subtle, as it can often go unnoticed; however, understanding that "each" necessitates a singular noun illuminates why "furniture" stands out as the incorrect option. The other words—'is', 'percent', and 'regular price'—are appropriate in their contexts. Thus, option A, "furniture," is the correct answer due to its grammatical inconsistency with the preceding singular determiner "each."
