The answer is B, structures for growing food in or near cities.In order for a city to survive and thrive, it is a must to have food and water the most. Then, shelter and communications, etc. could be built next.
The most important thing for the survival of the rapidly growing population in the capital city is the food. The food is the very basic need of an individual. The other facilities needed by the population, such as recreational spots, better communication and transportation systems are all secondary to the food. The lack of food will lead to starvation and ultimately death.
Hence, the correct answer is option (b) - structures for growing food in or near cities.
