Read the excerpt. i will arise and go now, for always night and day i hear lake water lapping with low sounds by the shore: while i stand on the roadway, or on the pavements gray, i hear it in the deep heart’s core. what emotion does the speaker in “the lake isle of innisfree” by william butler yeats feel? bitterness hope mourning regret

I think it is the third option

Mourning

Explanation:

The tone is dull and negative, it can't be hope for that reason. It also can't be regret or bitterness because the speaker doesn't express any regrets or bad feelings toward anything. so that answer *must* be mourning.

Hope I could help!
