The Metamorphosis deviate from the standard structure of Freytag's pyramid because more than one scene can be considered the climax.
The standard structure of Freytag's pyramid is :
-Exposition
-Rising Action
-Climax
-Falling Action
-Resolution
Having more than one climax makes a story or plot to have a different structure, as we can see in The Metamorphosis.
d or b hope that helps any question feel free to text me

A flashback tells something from the past so the answer would have to be (A) this is because of the use of the word recall. In every other option the verb is present or future tense instead of past tense.
