Which of the following best illustrates a barrier to social mobility?

A barrier to social mobility is something that makes it difficult for people to move up in society, especially in terms of wealth or status. For example, if a child grows up in a low-income family, they might not have access to good schools or extra learning opportunities, which can limit their chances of getting a well-paying job later on. This lack of resources can keep them stuck in the same economic situation as their parents. Another example is discrimination based on race or gender, which can prevent individuals from getting jobs or promotions, regardless of their skills or hard work. These barriers can create a cycle where people find it hard to improve their lives and achieve their goals.
