I believe that the correct answer is the last option. In the poem “ A Valentine” by Edgar Allan Poe the element from the poem to which words treasure, talisman, and three eloquent words refer is the Valentine's name. This poem represents a riddle to which the answer is the Valentine’s name, as its stated in the lines: “For her this rhyme is penned whose luminous eyes,/Brightly expressive as the twins of Leda,/Shall find her own sweet name, that nestling lies/ … You will not read the riddle, though you do the best you can do.”
