Which of the following quotes from douglass's speech is an example of a periodic sentence?

a. it fetters your progress; it is the enemy of improvement, the deadly
foe of education; it fosters pride; it breeds insolence; it promotes
vice; it shelters crime; it is a curse to the earth that supports it, and
yet, you cling to it, as if it were the sheet anchor of all your hopes.

b. heat and sorrow have nearly consumed their strength; suddenly
you hear a quick snap, like the discharge of a rifle; the fetters
clank, and the chain rattles simultaneously; your ears are saluted
with a scream, that seems to have torn its way to the center of
your soul!

c. cast one glance, if you , upon that young mother, whose
shoulders are bare to the scorching sun, her briny tears falling on
the brow of the babe in her arms.

d. go where you may, search where you will, roam through all the
monarchies and despotism of the old world, travel through south
america, search out every abuse, and when you have found the
last, lay your facts by the side of the everyday practices of this
nation, and you will say with me, that, for revolting barbarity and
shameless hypocrisy, america reigns without a rival.
