Right choice is (d) Every megaspore that is produced after meiosis undergoes mitosis to form a female gametophyte

For explanation: On reaching female gametophyte, the pollen grains produce a tube like structure that carries sperms to the egg. Fertilization in Gymnosperms can also be described as siphonogamic. Ovules in Gymnosperms are unprotected unlike that of angiosperms. Among the four megaspores that are formed after meiosis only one megaspore is functional and the rest becomes defunct.
