The answer is: Friar Laurence uses words like "waste" and "forsaken" to show that he disapproves of Romeo's change of heart.
In the excerpt from "Romeo and Juliet", by William Shakespeare, Friar Lawrence cannot believe Romeo has changed his mind so quickly, since he was deeply in love with Rosaline a very short time ago. He also mentions Romeo's tears and crying over Rosaline, so at first he feels doubful and looks down at Romeo.
The rest of the options are incorrect because in the passage Friar Lawrence makes no reference to Juliet; he only questions how Romeo has fallen out of love with Rosaline.
