The correct answer is: A. residue of material.
Scrap is the residue of material that is left over after a manufacturing process. It can be caused by a variety of factors, such as defects in the material, errors in the manufacturing process, or changes in the design of the product. Scrap can also be generated as a result of normal wear and tear on products.
Scrap can be a valuable resource, and it can be recycled or reused in a variety of ways. For example, it can be used to make new products, or it can be used as a fuel source. Scrap can also be used to create art or sculptures.
There are a number of ways to reduce the amount of scrap that is generated. One way is to improve the quality of the materials that are used in the manufacturing process. Another way is to improve the manufacturing process itself. Finally, it is important to design products that are less likely to generate scrap.
Scrap is a valuable resource, and it is important to manage it effectively. By reducing the amount of scrap that is generated, and by recycling or reusing scrap, we can help to protect the environment and conserve resources.
Here is a brief explanation of each option:
- Option A: Residue of material. Scrap is the residue of material that is left over after a manufacturing process. It can be caused by a variety of factors, such as defects in the material, errors in the manufacturing process, or changes in the design of the product. Scrap can also be generated as a result of normal wear and tear on products.
- Option B: Wastage of material. Wastage is the act of using or consuming something in a wasteful way. In the context of manufacturing, wastage can refer to the use of materials that are not necessary for the production of a product. It can also refer to the loss of materials during the manufacturing process.
- Option C: Surplus material. Surplus material is material that is left over after a manufacturing process. It can be caused by a variety of factors, such as overproduction, changes in the design of the product, or changes in the demand for the product. Surplus material can be sold or recycled.
- Option D: Abnormal loss of material. Abnormal loss of material is the loss of material that is not expected or planned for. It can be caused by a variety of factors, such as accidents, theft, or natural disasters. Abnormal loss of material can be a significant cost to a business.
