Answer:
Juliet: “My bounty is as boundless as the sea.”
Step-by-step explanation:
Visual motif is a visual pattern, which in the context of Romeo & Juliet, means the use of descriptive language focusing on the sense of sight. All the options except for Juliet's dialogue, focuses on this, with Mercutio's "Blind is ....", Romeo's "What light through younder ...", and Friar Laurence's "The grey-eyed morn smiles ...".
Juliet's part, instead is a form of simile, describing how her bounty is like the boundless sea - but it does not look like one.
