In angiosperm, the haploid, diploid and triploid structures of a fertilized embryo sac sequentially are:

  1. A
    Synergids, Primary endosperm nucleus and zygote
  2. B
    Antipodals, synergids, and primary endosperm nucleus
  3. C
    Synergids, Zygote and Primary endosperm nucleus
  4. D
    Synergids, antipodals and Polar nuclei

Solution & Step-by-step Explanation

ShutterstockHaploid (): Synergids (part of the gametophyte).Diploid (): Zygote (formed by syngamy of egg sperm).Triploid (): Primary Endosperm Nucleus (PEN) (formed by triple fusion of two polar nuclei one sperm).The correct sequence is Synergids, Zygote, PEN.
