Question

. "Until then I am a red balloon tied to an anchor." This figure of speech is an example of:
A.
Metaphor
B.
Simile
C.
Personification
D.
Onomatopoeia

Answer 1

Here the writer is describing himself as a red ballon.
If he had written I was like a red balloon, then the figure of speech would be Simile
Personification= doesn't not fit the context, it is the giving of human traits to inanimate or non-living objects. He doesn't say anything about the balloon's emotions or physical gestures.

Onomatopoeia= it's not a figure of speech but word that phonetically imitates or suggests the source of the sound that it describes

So Metaphor remains which is the right choice.

Another example to help you understand:
Simile= He was like a lion in the battle
Metaphor= He was a lion in the battle
