Manufactured boards are available in standard sizes such as 2440 mm by 1220 mm (8 ft by 4 ft).

• A. Manufactured board
• B. Hardwood
• C. Blockboard
• D. Plywood

Answer: (A)

Manufactured boards are produced as large sheets and sold in standard dimensions. The 2440 mm by 1220 mm (8 ft by 4 ft) size is a common sheet size because working with uniform panels makes cutting, fitting, and transporting easier in furniture and construction. This standardization applies to the whole category of panel products, which includes plywood and blockboard, among others. Hardwood, by contrast, refers to natural solid timber, not a sheet material sold in fixed sheet sizes. Since the sentence describes the general category that comes in standard sheet sizes, the term that fits best is the broad category of manufactured board.
