While all the options listed can contribute to better equality for people around the world, "equal opportunities for education from beginning to end" is often considered the most fundamental. Education is a critical driver of socioeconomic growth and personal development. Ensuring equal access to quality education allows individuals to acquire the skills and knowledge necessary to compete in the job market, start businesses, and contribute to their communities. It can also help break the cycle of poverty and empower marginalized groups, creating a more equitable society overall.
That said, each of the options addresses important aspects of equality, and a comprehensive approach that includes all of them would likely yield the best results in promoting equality worldwide.
