Answer :
Answer: Centre of equal daughters equal sons
Explanation: It is basically asking what is the reasoning that America is the heart or center of democracy.
The line that appropriately explains the meaning of America as the heart of democracy is option (d): "Centre of equal daughters equal sons."
Why is America called the heart of democracy?
Whitman was primarily interested in the American democratic experiment and its capacity to create "from of many, one," even at a high price like the Civil War and the shaky Reconstruction.
Whitman believed that in a democratic society, everyone should be treated equally and that people should respect and tolerate one another's differences.
The sons and daughters for whom the "sitting Mother" is the "centre" are equalised in Whitman's "America."
Whitman therefore offers a further early proclamation of gender equality, extending it to include people of all ages— "all alike endear'd, ungrown, grown, old, or young."
