The relationship among the three pillars is that sustainability only works when environmental protection, economic health, and social equity are pursued together. Each pillar supports the others, so long-term well-being depends on balancing ecological protection, economic viability, and fairness in society. If one pillar is neglected, the gains in the others are undermined: environmental gains may collapse without economic support or social buy-in; economic growth without environmental safeguards or social fairness can create harm and instability; and social inequities can erode trust and undermine both environmental and economic goals.

That’s why the best statement is that all three pillars must be pursued together to ensure long-term well-being; neglecting one undermines the others. The other options suggest focusing on only one pillar, prioritizing one over the others, or ignoring social equity, which would all jeopardize sustainable development in the long run.
