Solution

The correct option is A Vertically with morphological apical end upwards
In leaf and stem cuttings, the explant is taken from the apical portion of leaf or stem as it has a meristematic cell which has active nucleus and cytoplasm. The meristematic cell divides rapidly when cultured on nutrient media and provides virus-free plant. When the apical portion of the leaf or stem culture is sown, it is sown vertically with morphological apical end upwards to ensure maximum growth by keeping the meristematic cell at the top.
So, the correct answer is option A.
