(b) Citizens feel empowered to determine policies.
When a democratic government involves citizens and experts in making environment-friendly policies, citizens gain a sense of ownership and empowerment in the decision-making process.
The key idea here is that democracy's positive outcome is citizen participation and empowerment. Options (a), (c), and (d) describe situations where government, corporates, or market forces dominate — these are not positive democratic outcomes. The question specifically says policies are made with the help of citizens and experts, pointing directly to option (b). Examiners look for understanding that democracy strengthens citizens' role in governance.
