Answer:
Option D, the proximity of the space to the city's population
Explanation:
An urban planner or city planner must focus on providing green space near to the place of residence. There is no logic of providing green spaces at far distance as then large distance would discourage its usage. If a green space is near to the people residence, they will use it or else their provisions go in vain.
Also, there must be adequate space based on the development guidelines of the city or state.
All the urban designers must focus on providing a green space based on minimum green space requirement per person and also provide such open spaces at a place which are near to the living areas.
