C. Housing prices in cities generally increase more quickly than
anywhere else.
Explanation:
An investment is an activity that leads to an increase in value or wealth. A good investment is one that appreciates its value with a big percentage in a short period. Houses are always in demand in big cities. For this reason, their prices are ever appreciating.
Buying a single-family home in a city is a good investment decision because it is bound to appreciate in value. Should one decide to sell it later, they are highly likely to receive a much higher amount than they paid for it. The probability of making some good profits from the house is high.
