sagacity means good judgement while bestowing means providing
Option D is correct. Most interpretations agree that in Metamorphosis, the Kafkaesque describes a situation of Gregor struggling with his family after the transformation. Gregor is the one carrying with his kafkaesque existence and learning how to put up with himself, but his family rejects him. After Gregor dies, his family feels relieved, rather than sad.
In my view purpose and point of view are very important when writing a biography.
