Answer:
B) "I mustn't act like a baby--I must try to be strong..."
Step-by-step explanation:
Even without reading this book, I can tell that Option B is a simile because a simile is a comparison between 2 unalike objects using the words "like" and/or "as".
Option A is personification because cars cannot literally crawl. This option is incorrect.
Option B is a simile because it uses the word "like" to compare them self with a baby. This is correct.
Option C is a hyperbole because lungs cannot be immediately solidified and stop working. This is incorrect.
Option D is an onomatopoeia because of the first word "Crack". This is incorrect.
Thus, making B the correct option. Hope this helps! :)
