Solution

The correct option is A One of the synergids
Entry of pollen tube into the embryo sac - the pollen tube enters into the embryo sac only through the micropylar end either passing in between egg cell and synergid. Before the entry of pollen tube into the embryo sac, one of the synergids begin to degenerate. This cell serves as the site for the entry of pollen tube.
