The correct answer is D. (b) and (c).
A discrete parts process is a manufacturing process that produces individual pieces or parts, as opposed to a continuous process, which produces a continuous flow of material. Discrete parts processes are often encountered in manufacturing, as they are well-suited for producing a variety of different products. They are also typically a repetitive series of operations, as the same steps are often repeated to produce each individual part.
Option A is incorrect because discrete parts processes and continuous processes are fundamentally different. Discrete parts processes produce individual pieces or parts, while continuous processes produce a continuous flow of material.
Option B is correct because discrete parts processes are often encountered in manufacturing. They are well-suited for producing a variety of different products, as they can be easily adapted to produce new products or to change the production of existing products.
Option C is correct because discrete parts processes are typically a repetitive series of operations. The same steps are often repeated to produce each individual part. This can be seen in the assembly line, where each worker performs a specific task on the product as it moves down the line.
Option E is incorrect because both options B and C are correct.
