Selaginella and Salvinia are considered to represent
a significant step toward evolution of seed habit
because
(a) female gametophyte is free and gets dispersed
like seeds
(b) female gametophyte lacks archegonia
(c) megaspores possess endosperm and embryo
surrounded by seed coat
(d) embryo develops in female gametophyte which
is retained on parent sporophyte.
