Solution

The correct option is B Pinnate
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. Pinnate venation is also called as unicostate venation. In this, the lamina has a single principal vein or midrib. It produces lateral veins. Palmate venation is also called as multicostate venation. In this, lamina has more than one principal vein.
Thus, the correct answer is 'Pinnate.'
