Your answer (4) is correct.
From the pictures, flower A only has female parts (stigma, style & ovary), it does not have anther to produce pollen grains. Whereas flower B has anthers to produce pollen grains and since it is higher than the petals, it is pollinated by wind. Hence it is only correct that the pollen grains from flower B is carried by wind to the stigma of flower A.
