The seven types of waste identified in Lean methodology are accurately listed in the provided answer. Overproduction refers to producing more than is needed or before it is needed, which can lead to excess inventory and increased storage costs. Waiting involves idle time that results when processes are delayed, preventing other tasks from being completed. Transport waste includes unnecessary movement of materials or products, which does not add value to the product. Extra Processing refers to steps in a production process that do not add value, such as rework or excess steps. Inventory waste includes having more stock than what is necessary to meet customer demand, which ties up capital and storage space. Motion waste involves unnecessary movements of people, such as walking or reaching, which can lead to inefficiencies. Finally, defects are anything that does not meet quality standards, requiring correction, rework, or replacement.

Each of these wastes represents an area where businesses can improve efficiency and reduce costs, aligning perfectly with the principles of Lean methodology aimed at enhancing value by minimizing waste. The other options contain various terms and combinations that do not accurately reflect the established seven types of waste recognized in Lean practices.
