ANSWER:
The correct option is A: Putting a "parking garage" on an unused lot inside a city.
EXPLANATION:
- Infill takes place when a land or area not being used is put to use for public good. This does not mean that an area which is old is converted to a new area or is brought to use.
- The infill of an unused area by putting a parking garage simply brings the area under use. However, if the area or land was under cultivation or had an old building on it and was converted to a parking lot, it would not have been infill.
