Solution

The correct option is C Lateral Terminal Axial
Monocotyledonous embryos have a single cotyledon which is initiated very early.The position of plumule in monocot embryo is on the 'lateral side' of the primary axis.The position of radical is terminal.During development the differential growth in the cotyledon results in a lateral shoot apical meristem. Monocot contains one large shield-shaped cotyledons known as scutellum. Cotyledon is in apical position.
Hence, the correct answer is (C)
