Answer:
Your answer to fill in the blank is C. being realistic about love because in love you love the person with all of your heart and you are honest which is being realistic.
Step-by-step explanation:
This is the correct answer I believe because the lines ¨she cannot fade ¨ means that she cant disappear or leave over time because love is a promise. ¨ forever wilt thou love, and she be fair¨. Meaning that she will love and the definition of fair is someone or something that is light in color, attractive, honest or clear and sunny. ... An example of fair is a beautiful woman. An example of fair is an unbiased judge. I hope this makes sense :)
