The correct answer is C. When available land is limited.
Explanation: Upward growth of cities, also known as vertical growth, typically occurs when there is a scarcity of land due to high population density or geographical constraints. In such cases, cities build upwards to accommodate more people and businesses, leading to the construction of taller buildings and skyscrapers. This situation arises when horizontal expansion is not feasible.
