Which scenario best illustrates the concept of intergenerational mobility?

Intergenerational mobility refers to how a person's social and economic status can change compared to their parents' status. For example, if a child grows up in a low-income family but works hard in school, earns a college degree, and eventually becomes a successful doctor, this shows upward intergenerational mobility. This scenario illustrates how the child's achievements allow them to rise above the economic position of their parents. It highlights that despite their background, opportunities and personal effort can lead to a better life. In contrast, if the child stays in the same low-income situation, that would represent little to no mobility between generations.
