The correct answer to this open question is the following.
Although there are no options attached we can say the following.
A definition of American civil religion could be a theory developed in sociology that idolized the idea of Americans in the United States territory, and the fight and effort to call America their own. It is constituted by a series of values that strengthen the social integration of people into the American culture.
We can trace the term back to 1967 when a sociologist named Robert Bellah coined the term in the article "Civil Religion in America." He wrote that this concept was the result of the patriotic belief systems and culture shared by the American people.
Some examples of civil religion could be the series of celebrations of the 4 of July to celebrate Independence Day or other festivities such as Memorial Day or Veterans Day.
This culture and sense of Patriotism fostered what is known as American exceptionalism, the idea that the United States is special, unique, far superior to other countries, and that gives the country the faculty to influence, control, or transform other countries.
