Answer :
Final answer:
The height gauge is the most accurate tool for measuring the height of two or more workpieces, offering high precision necessary for determining if pieces have the same thickness. Thus the correct option is option b. Height gauge.
Explanation:
The most accurate gauge for measuring the height of two or more workpieces is the height gauge. Unlike other measuring tools, the height gauge is specifically designed for measuring the height of objects and offers high precision, making it ideal for tasks that require measuring two pieces to check if they have the same thickness. Vernier calipers, micrometers, and dial indicators also provide precise measurements but are better suited for measuring dimensions other than height, such as width or depth. For ensuring two pieces of glass or any material are of the same height, the height gauge stands out as the most appropriate tool for the job.
