Solution

The correct option is A Grasses and Palms
Venation is the arrangement of veins on the leaves. It is basically of 2 types, reticulate and parallel. Reticulate venation involves irregular distribution of veins to form a network. Parallel venation involves the veins running parallel to each other. In pinnate or unicostate venation, the lamina has a single principal vein or midrib. It produces lateral veins. In palmate or multicostate venation, lamina has more than one principal vein. In Grasses and Palms, the venation is multicostate parallel. 
Thus, the correct answer is 'Grasses and Palms.'
