During the development of dicot embryo, initially the dicot embryo is globular and undifferentiated. Early embryo with radial symmetry is called proembryo. It is transformed into embryo with the development of radicle, plumule and cotyledons. Two cotyledons differentiate from the sides with a faint plumule in the centre. At this time the embryo becomes heart-shaped. Part of embryo axis between the plumule and cotyledonary node is epicotyl (above the level of cotyledons) while the part between radicle and cotyledonary node is called hypocotyi (below the level of cotyledons). The single cotyledon of monocotyledonous seed {e.g. maize grain) is called scutellum. It occupies the major portion of the embryo regions of grain.

Statement (i): During the development of a dicot embryo, heart-shaped embryo is followed by globular embryo.
This statement is incorrect. The development of a dicot embryo involves several stages, including the globular stage, heart-shaped stage, and torpedo-shaped stage. The globular stage is the initial stage of development, followed by the heart-shaped stage, and finally the torpedo-shaped stage.

Statement (ii): The part of embryonal axis above the level of cotyledons is epicotyl, while the part below the level of cotyledons is hypocotyl.
This statement is correct. The embryonal axis is the main axis of the embryo. It consists of three regions: the epicotyl, the hypocotyl, and the radicle. The epicotyl is the region of the embryonal axis above the level of cotyledons, while the hypocotyl is the region below the level of cotyledons.

Statement (iii): Monocot seeds possess a single cotyledon represented by scutellum.
This statement is correct. Monocots, such as grasses and lilies, have seeds that contain a single cotyledon. The cotyledon in monocots is known as the scutellum, which is a modified cotyledon that is specialized for absorbing nutrients from the endosperm during germination.

Therefore, the correct statements are (ii) and (iii). Option (b) is the correct answer.
