Answer:
(d) in midrib and its branches
Step-by-step explanation:
The stalk, or petiole, is the part of the leaf that connects it to the stem.
The lamina is the flat, green part of the leaf.
The midrib is the main vein that runs through the center of the leaf.
The branches are the smaller veins that extend from the midrib.
So, the answer is (d). The vascular tissue in leaves is located in the midrib and its branches.
