Alliteration is the repetition of the same sound at the beginning of a group of words. In "summer-weight sportcoats" the "s" sound is repeated. In "polished pine" the "p" sound is repeated.
Allusion is a reference to another published work. Irony is when the opposite of what is said or expected happens. A metaphor is the comparison between two different things without using like or as. None of these other options are valid.
"Never forget what you are, for surely the world will not. Make it your strength. Then it can never be your weakness. Armour yourself in it, and it will never be used to hurt you.”
