Which speakers statement best reflects the ideas of the enlightenment

I found some of the missing information about this question. 

Speaker A: Good government stresses the importance of the nation and accepts the rights of the individual only if the interests of the individual are the same as those of the nation.

Speaker B: The person of the king is sacred and to attack him in any way is to attack religion itself. The respect given to a king is religious in nature.

Speaker C: All human beings are born free and equal with a right to life and liberty. It is the duty of government to protect these natural rights of its citizens.

Speaker D: Our goal will not be achieved by democracy or liberal reforms, but by blood and iron. Only then will we be successful. No nation achieves greatness or unity without the traumatic experiences of war.

The choices are 1. A  2. B  3. C  4. D. The answer is  3. letter C

Enlightenment period is centered on freedom and having the right to life as well as liberty. It sprung out during the repressive times among the people during the reign of the monarchy who used their power as a privilege to gain wealth. Letter C. expressed the desire of the enlightenment period.
