The correct answer is: His sisters and his mother are very fond of him.
His sisters and his mother see him as a hero. His sisters look up to him and are proud of him. His mother is proud of him and likes to take care of him even though he is older now and come home from the war. They are all fond of each other.
I would say because they're in a set of triplets? This is because there are three babies that are born from the same mother on the same day, and two of those babies would be born on the same day... but they would have to be twins... so it isn't possible unless they are triplets.
