Constitutional Design

Here are different opinions about what made India a democracy.
How much importance would you give to each of these factors?
a Democracy in India is a gift of the British rulers. We received training to work with representative legislative institutions under the British rule.
b Freedom Struggle challenged the colonial exploitation and denial of different freedoms to Indians. Free India could not be anything but democratic.
c We were lucky to have leaders who had democratic convictions. The denial of democracy in several other newly independent countries shows the important role of these leaders.
