Answer: b) The total market value of all final goods and services produced within a country's borders in a given period.
Explanation: GDP measures the value of all goods and services produced within a country's borders in a specific time period, regardless of whether the producer is domestic or foreign.

2. Match the following economic concepts with their definitions:

Answer: c) Depreciation
Explanation: NDP is derived by subtracting depreciation (the loss of value of capital goods) from GDP.
