    multiple foci are present in zone plate.. and see the formula of rn ( radius of circles that formed) , rn is proportional to wavelength means red colour has large radius than voilet colour so high wavelength ( red) are far from center or focus.... option 3,4 are correct.. not sure about 2. but 1 is definitely wrong... see the attached pages too.... best regards..
