b. Ye blooming plants of human race divine

The line that contains an allusion to the story of Adam and Eve is option d. "Its transient sweetness turns to endless pain." This line alludes to the biblical story of Adam and Eve, where they partook of the forbidden fruit that promised sweetness but led to their expulsion from the Garden of Eden and the suffering that followed.

The line that contains an allusion to the story of Adam and Eve is option c. "By you be shun'd, nor once remit your guard."

To confirm this, we need to understand what the story of Adam and Eve is about. In the Bible, Adam and Eve were the first man and woman created by God. They lived in the Garden of Eden until they were tempted by a serpent to eat the forbidden fruit from the Tree of Knowledge. This act of disobedience led to their expulsion from paradise.

Now, let's analyze option c: "By you be shun'd, nor once remit your guard." The phrase "be shun'd" means to be avoided or kept away from. The mention of "remit your guard" implies the need for constant vigilance or caution. This line, when read in context, suggests that something should be avoided and guarded against. It alludes to the story of Adam and Eve, where they were warned to stay away from the forbidden fruit and should have been on guard against temptation.

By identifying the specific references and making connections to the story of Adam and Eve, we can conclude that the line "By you be shun'd, nor once remit your guard" contains an allusion to the story of Adam and Eve.
