    D) 42, 28, 14, 28, 14

    Correct Answer: C

    Solution :

    [c] Integument is a diploid cell 2n = 2 x 14 = 28 Antipodal cells are haploid n = 14 Embryo is diploid \[\therefore \] 2n = 2 x 14 = 28 Endosperm is triploid \[\therefore \] 3n = 3 x 14 = 42 Nucellus is diploid \[\therefore \] 2n = 2 x 14 = 28
