A government that consistently ignores the demands of major pressure groups and dismisses prevailing public opinion is MOST likely to experience

Legitimacy in a democratic system depends significantly on government responsiveness to citizens' demands and public opinion. When a government persistently disregards organized pressure groups and widespread public sentiment, it erodes public trust and consent, which are the foundations of legitimate authority, thereby risking civil unrest, mass protests, or broader political instability. Legislative efficiency, foreign investment, and judicial independence are not directly determined by this relationship.
