The correct option is A Kaju Barfi and Sohan Halwa
If package 4 contains Petha and Cham Cham, then Kaju Barfi is in package 1 and 3, packages 2 and 5 contain Rasgulla. Also, since Gulab Jamun can only be to the right of Kaju Barfi, it will be packed in package 5 along with Rasgulla. Hence, package 1 must contain Sohan Halwa.
