Which lines from the poem clarify the theme of "Love is more important than wealth" "Though I am old with wandering" (line 18)

"I will find out where she has gone." (line 20)

"And pluck till time and times are done" (line 22)

"Because a fire was in my head," (line 2)

"But something rustled on the floor" (line 11)

B.  I will find out where she has gone (line 20)

Explanation:

"The Song of Wandering Aengus" is a poem written by William Buttler Yeats. The poem is about finding the true love. One day the poet goes into the woods to find peace, rather, he finds his true love which vanishes into the woods. The poet is now an old man and still trying to find the woman.

The line that signifies the theme of the poem, Love is more important than wealth, is line 20. In this line, the poet is still persistent in finding the woman who called out his name and vanished into the woods. This also means that the man is eager to seek the love than wealth.

Thus, option B is correct.
