Which describes mass production?

• A. delivered when needed so no warehousing to store parts
• B. the making of a single, unique product
• C. the making of a batch of products
• D. production of goods in large numbers through the use of machinery and assembly lines

Answer: (D)

Mass production means producing goods in very large quantities using machinery and assembly lines, which allows standard parts and processes to run continuously and with minimal variation. This setup drives high output and lower cost per unit because of economies of scale and automated or semi-automated work, making it ideal for delivering large volumes consistently. The other descriptions describe different approaches: delivering items just-in-time focuses on inventory management rather than volume, making a single unique product is bespoke production, and making a batch refers to producing a limited quantity before switching to another product.
