a. Most new social policy ideas are tried by one or two states before the other states or the federal government adopt the ideas.

Explanation:

Social ideas that can have an effect on the society are implemented by one or two states and if the idea or policy turns out to be beneficial for the people then it is adopted by others. For instance, the legalization of Marijuana was first done by Washington and Colorado in 2012. The idea started in 19th century when women voting rights were first introduced by Wyoming and California which lead to a national call for rights. Hence, option A is the correct option that new social policy ideas are tried by one or two states before the other states or the federal government adopt the ideas.
