The answer is indeed letter D. her tedious and never-ending chores.
Explanation:
"A Servant to Servants" is a poem by Robert Frost. The poem's speaker is a woman who's overwhelmed by the life she lives. She's constantly snowed under household chores, never satisfied with what she experiences, never brave enough to let go and try a more adventurous lifestyle. She sees a lake from her kitchen window and wonders what is feels like to those who "take the lake", those who travel, who see new things. The way the poem is structured, with no interruptions - no division into stanzas - is probably a reflection of her own mind. Full of thoughts and despaired dreams, she unravels them to her listener avidly, as if she doesn't know when she might have the chance to talk like this again. The poem goes full circle: even though she mentions her own and her uncle's mental illness and her husband's decision to move with her to the lake, she starts and ends by lamenting her tedious life.
It’s rest I want—there, I have said it out—
From cooking meals for hungry hired men
And washing dishes after them—from doing
Things over and over that just won’t stay done.
By good rights I ought not to have so much
Put on me, but there seems no other way.
[...]
I almost think if I could do like you,
Drop everything and live out on the ground—
[...]
I haven’t courage for a risk like that.
Bless you, of course, you’re keeping me from work,
But the thing of it is, I need to be kept.
There’s work enough to do—there’s always that;
But behind’s behind. The worst that you can do
Is set me back a little more behind.
I sha’n’t catch up in this world, anyway.
