Read ths excerpt from “Break, Break, Break” by Alfred Loryd Tennyson. What is the theme of the poem?

Break, break, break,
On thy cold gray stones, O Sea!
And I would that my tongue could utter
The thoughts that arise in me.

O well for the fisherman's boy,
That he shouts with his sister at play!
O well for the sailor lad,
That he sings in his boat on the bay!

And the stately ships go on
To their haven under the hill:
But O for the touch of a vanish'd hand,
And the sound of a voice that is still!

Break, break, break,
At the foot of thy crags, O Sea!
But the tender grace of a day that is dead
Will never come back to me.

A. Life seems like the endless ocean
B. One man's grief cannot stop progress
C. A moment lost in time does not return
D. People do not understand the true meaning of life
