Which of the following factors best exemplifies a systemic barrier to social mobility?

A systemic barrier to social mobility is something built into society that makes it hard for people to improve their economic status. One key example is the unequal access to quality education. In many areas, schools in wealthier neighborhoods often have better resources, experienced teachers, and more extracurricular activities than schools in poorer areas. This means that children from lower-income families may not get the same opportunities to learn and succeed. For instance, if a student from a low-income neighborhood cannot access advanced classes or tutoring, they might struggle to get into a good college, which can limit their future job opportunities.
