Interchangeable parts are defined as which of the following?

• A. Assembly line
• B. Interchangeable parts
• C. Mass production
• D. Standardization

Answer: (B)

Interchangeable parts refer to standardized components that are identical and can be substituted for one another in manufacturing. That definition is exactly what the term describes, so choosing the concept itself is the best fit. This idea is what allows rapid assembly and easy repair, and it underpins the growth of mass production and uniformity in factories. The other options are related ideas: an assembly line is a method for putting parts together, mass production is the high-volume outcome, and standardization is the broader process of making parts uniform. But only the phrase interchangeable parts directly captures the idea of identical, replaceable components that fit across different products.
