I love that poem, what he means is nothing good can stay, it will fad or disappear, after a wile. hence why he said this
Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
and it means, when fall comes the leafs will fall, "maybe a flower but not more that an hour".
Answer is option "B".
The correct format for an MLA in-text citation for an article with no known author is ("Title" page).
MLA stands for "modern language association".
The "Title" is the shortened title of the work. When the work is short like an article then the tile enclosed in the quotation is used and when the work is long like plays, books etc then the title is italicized instead of enclosing it in quotation marks.
