Answer: This is an example of a (A) common-law marriage.
Step-by-step explanation: A common-law marriage unites a couple that has been living together for many years but has never been officially married nor given a marriage license. However, two people that share a common-law marriage present themselves and act as a married couple. In that way, Jim and Lara, who have a romantic relationship and have shared a home for 10 years but do not have a marriage license nor have been married, are an example of a common-law marriage.
