Answer:
The correct answer is option d.
Step-by-step explanation:
An apartment complex converts to a condominium so that the former renters are now owners of their housing units.
A current estimate of the value of the condominium owners' housing services is the same as the rent they previously paid.
This will cause no change in GDP. This is because earlier rent was being paid which was included in GDP. But now that the former renters are the owners. The rent is replaced by the imputed rent or the value of condominium owners' housing services. Since the imputed rent is the same as the rent paid earlier. The GDP will remain unaffected.
