01 On what basis is a functional region formed in human geography?
Answer and explanation
Correct answer: B. On the interaction between a centre and its connected areas
Explanation: A functional region is organised around a central place and the flows or interactions connecting that centre with surrounding areas. The centre may provide employment, markets, education, healthcare, administration or transport services, while the surrounding zone depends on or interacts with it. Option B is correct because it identifies the relationship between a node and its area of influence. Similar rocks and rainfall help define physical or formal regions, and a political boundary defines an administrative region. A functional region is therefore based on activity, connection and influence rather than simple uniformity.
