Answer: In angiosperms, the megaspore mother cell undergoes one meiotic division to form four haploid megaspores, out of which only one survives. This functional megaspore then undergoes three mitotic divisions to form the 8-nucleate mature female gametophyte (embryo sac).

Hence, the correct answer is Option (4).
