Final answer:
The World Bank approach to combating child labor is by tackling the sources of poverty, thus option (b). Addressing poverty through educational initiatives, economic support, and legislative efforts historically has been effective in reducing child labor.
Step-by-step explanation:
The World Bank's approach to combating child labor is focused on tackling the sources of poverty, which is option (b). This strategy is based on the understanding that child labor is often a symptom of broader socioeconomic issues, including poverty. By addressing these underlying causes, the World Bank aims to reduce the necessity for families to rely on their children's income. Economic growth, increasing human capital through education and health initiatives, and providing social safety nets are some of the ways the World Bank seeks to tackle poverty and, consequently, child labor.
History shows that mandates for compulsory education and legislation were crucial in reducing formal wage work by children in the past. Efforts like increasing resources for families, improving labor laws, and incentivizing work can have significant impacts. Moreover, many countries have moral objections to child labor and have taken legal steps to reduce it by restricting imports from countries where child labor is prevalent.
