Hint:Specialized cells that lie adjacent to the egg cell in the female gametophyte. They play a major role in pollen tube guidance and function. They are also essential for the cessation of pollen tube growth and the release of male gametes.

Complete answer:Compatible pollination results in the production of the pollen tube. The pollen tube doesn’t grow beyond the synergid cells. The male gametes in the pollen tube are discharged into the synergid cells from where the first male gamete is transferred to the egg cell of the embryo sac. The other male gamete is transferred to the central cell through the cytoplasmic current. The male gamete fuses with the egg cell and completes syngamy. This results in the formation of a zygote which is a diploid cell. The other male gamete fuses with the two polar nuclei in the central cell. This fusion results in the production of the primary endosperm nucleus (PEN). This fusion of three haploid nuclei is known as triple fusion. The syngamy and triple fusion together are known as double fertilization.
Hence, the correct option is D Synergids.

Note:Synergid cells are part of the egg apparatus in angiosperms. They are located in the female gametophyte that is essential for reproduction. They form a thick-walled structure at the micropylar end known as the filiform apparatus. Its function is to guide the entry of the pollen tube and the release of male gametes.
