Which of the following describes 'invisible imports'?

Invisible imports refer to the purchase of services from foreign businesses. This term encompasses a wide range of non-tangible commodities, such as software, consulting services, legal advice, tourism, and entertainment that are acquired by a country but do not involve physical products being imported into that country.

When a business or individual pays for these services from abroad, it is considered an invisible import because, unlike physical goods, the services themselves do not cross borders in the traditional sense. This concept is an important part of understanding international trade, as it highlights that a substantial portion of economic interactions occurs through services rather than just goods.

The other options revolve around tangible goods or tangible export processes, which clearly differentiate them from the concept of invisible imports. Understanding these categories is crucial for analyzing a country's balance of payments and its economic interactions on a global scale.
