Final answer:
Patrick Henry uses D) metaphor and C) personification as rhetorical strategies in this line.
Step-by-step explanation:
In this line from Patrick Henry's speech, he most clearly uses metaphor and personification as rhetorical strategies.
The phrase 'listen to the song of the siren till she transforms us into beasts' is a metaphor, comparing the act of being deceived by false promises to being transformed into beasts.
The use of personification is evident in the personification of the siren, attributing human-like qualities to her song and suggesting its power to deceive.
