Visible exports refer to what?

Visible exports refer to tangible goods that are produced within a country and then sold to foreign markets. They are called "visible" because these products can be physically seen and transported, contrasting with services or intangible items, often referred to as "invisible exports." In this context, the correct choice accurately describes the concept of visible exports as it highlights that Irish businesses are engaging in international trade by selling their products to foreign countries, thereby contributing to the national economy through increased revenue from these sales.

The other options do not accurately define visible exports. Domestic sales refer to transactions that occur within the country and do not involve foreign markets. Goods that are produced but not sold do not contribute to exports, as they remain unsold within the domestic market. Imports, on the other hand, represent goods brought into a country from abroad rather than exported goods. Thus, the emphasis on Irish businesses engaging in export activities aligns with the precise definition of visible exports.
