Which of the following is a feature of mass production?

Mass production is characterized by its use of specialized machinery that performs one specific job or task efficiently and consistently. This machinery is designed to handle high volumes of production with minimal changeover time, making it highly effective for producing large batches of standardized goods.

By utilizing specialized equipment, manufacturers can take advantage of economies of scale, resulting in lower per-unit costs as production volume increases. This approach contrasts with other production methods, which may require more versatile machinery or skilled labor capable of performing a variety of tasks, but at a higher cost and complexity.

The other options—requiring highly skilled workers, creating tailored products, and producing smaller quantities—do not align with the principles of mass production. Instead, mass production focuses on efficiency, standardization, and high output levels, which makes the use of specialized machinery a key feature of the process.
