Democracy’s superior virtue lies in the fact that it calls into activity

Democracy's strength is that it empowers ordinary citizens.

Option A: Democracy relies on informed participation through voting and provides liberty and freedom of expression, fostering intellectual growth and promoting values like justice and equality. This makes option A the most appropriate.

Option B: This option lacks a direct connection to the core principles of democracy.

Option C: The idea of a '“superior individual”' contradicts the democratic principle of equality and lacks a clear definition of 'dynamism and vision.'

Option D: This option is too narrow and doesn't encompass the broader participation that democracy encourages.

Hence, option A is the most suitable answer.
