C. Epidermal cells are generally parenchymatous and have small amount of cytoplasm with a large vacuole.
D. Terrestrial plants have a layer of cuticle on epidermis which prevents excessive water loss due to transpiration.
Hence, statement D is incorrect.
So, the correct answer is 'Epidermis usually lack cuticle in terrestrial plants'.
