The answer is A: A car the spouses bought together after the marriage.
Explanation for each option:
A. A car the spouses bought together after the marriage - This is considered community property because it was acquired during the marriage with funds that are presumed to be community property unless proven otherwise.
B. Income received from stocks owned by one spouse - In a community property state, income generated from separate property (such as stocks owned by one spouse before the marriage) is typically considered community property, unless there is a specific agreement stating otherwise. However, the question asks for what would be considered community property, and the car bought together is a more straightforward example.
C. Property inherited by one spouse after the marriage - Inheritances are generally considered separate property, even if received during the marriage, unless they are commingled with community property or there is an agreement to treat them as community property.
D. A coin collection bought by a spouse before the marriage - Property acquired before the marriage is typically considered separate property and not community property, unless it has been commingled with community property or there is an agreement to treat it as such.
