The correct answer is letter B
In sociology, social change is defined as significant changes in cultural symbols, norms of behavior, social organizations or value systems. According to sociologists, significant changes mean those that result in profound social consequences.
The changes we see in society are usually gradual. Unless it is a consequence of a natural disaster, such as an earthquake, or a political revolution, social changes become visible only months or years later. This type of social change can have several sources: technological changes, changes in the size or composition of the population and cultural changes. But some social changes occur thanks to the collective efforts of people working in social movements to change social policy or the very structure of the government.
A social movement is a sustained and organized effort that emphasizes some aspect of social change. Today, sociologists acknowledge the fundamental role that social movements play in inspiring dissatisfied members of society to seek social change. Social movements include those that aim to preserve the environment, promote racial justice, defend the rights of different segments of society or defend certain beliefs or principles.
Some examples of significant social changes that have had long-term impacts are the Industrial Revolution, the abolition of slavery and the feminist movement.
