Final answer:
The capital gains exclusions for single persons and married couples are $250,000 and $500,000 respectively, allowed every 7 years when the home is used as a primary residence for 3 out of the last 5 years.
Step-by-step explanation:
The correct answer is b) $250,000; $500,000; 7; 3.
Capital gains exclusions of $250,000 for single persons and $500,000 for married couples are allowed every 7 years, provided the home was used as a primary residence for 3 out of the last 5 years.
This means that if a single person sells their primary residence and makes a capital gain of up to $250,000, they would not have to pay taxes on that gain. Similarly, for married couples, the exclusion limit is $500,000.
