Translation:This is his neighbor Rosa.
جاري works too since you dont that you have to say "his neighbor"
No, جاري means "my neighbor" when referring to a male neighbor.
It seems to have a problem with the "Select the missing word" question. The sentence is backward so it appears as "روزا ..... هٰذِهِ" instead of "هٰذِهِ ...... روزا"
