In the context of economy, the term 'capital goods' refers to

Capital goods are tangible, durable assets that are used in the production process to manufacture other goods or provide services. They are considered one of the primary factors of production. Key characteristics include:

• Durability: Unlike raw materials or intermediate goods, capital goods are not consumed or transformed immediately during the production process; they have a long life span and are subject to depreciation.
• Productive Purpose: They are used by businesses to enhance productive capacity. Examples include machinery, industrial tools, factories, and commercial vehicles.

Option B describes consumer durables (like a personal television or car), which are intended for final consumption by households rather than for production. Option D is the correct definition as it highlights the role of these assets in producing further goods and services.
