Dear student,
Please find below the answer:

The correct option is (4).
The apoplast is a system of adjacent cell walls that are continuous, except at the Casparian strips of the endodermis.
The apoplast pathway involves the movement of water through the adjacent cell walls of the epidermis and cortex without entering the cytoplasm. The movement of water is restricted at the Casparian strips of the root endodermis. 

Hope this information clears your doubt.
