Why does Tennyson most likely make the fifth stanza longer than the third stanza of "The Charge of the Light Brigade?

a) to make each stanza in the poem slightly longer than the previous one

b)to show that the fifth stanza is more critical in understanding the poem

c) to draw the reader's focus to the fourth stanza where the battle occurs

d)to highlight the aftermath of the fierce battle waged in the fourth stanza
