Subjective: based on or influenced by personal experiences, beliefs, thoughts
I just copied and pasted this to see if anyone else had an answer, one person said B and that got 5 stars and a few thanks, so I'd go with B. Also, B seems objective because it is influenced by the person's feeling of the character.
The correct option is A.
From the statement given in option A, it can be seen that the character been talked about was formerly happy but he suddenly came to himself and become sad when he remember that he did not have a nose. All that he has, that were making him happy a moment ago were completely forgotten.
I would go with, It is necessary to have a list of needed items
That type of figurative language is a metaphor.
