Which quotation best shows how the author develops the theme that friendship does not depend on age?

"As he was about to leave, he asked: 'And where is the little girl, sir?'"

"...'Where did you get that eight-anna bit?' 'The Cabuliwallah gave it me,' said Mini cheerfully."

"...I was startled to find Mini, seated on a bench near the door, laughing and talking, with the great Cabuliwallah at her feet."

"And already the corner of her little sari was stuffed with almonds and raisins, the gift of her visitor."
