Final answer:
If a house has had better than average maintenance, rehabilitation, or modernization, its effective age is likely to be less than its chronological age.
Step-by-step explanation:
If a house has had better than average maintenance, rehabilitation, or modernization, its effective age probably will be less than its chronological age.
A house's chronological age refers to the number of years since it was built, while its effective age reflects the condition and upgrades it has undergone. If a house has been well-maintained or renovated, it will appear younger and more modern than its actual age. For example, a 50-year-old house that has undergone extensive renovations may have an effective age of 30 years or less.
Therefore, the correct answer is Option B) less than its chronological age.
