The example of vascular tissue in plant are
A. Xylem only
B. Phloem only
C. Both xylem and phloem
D. Epidermis cells

Hint: The vascular tissues are responsible for the transport of water and other nutrients which are required by the plants very efficiently from one part to the other part of the plant. The vascular system is composed of various different cells having a wide range of characters and functionality.

Complete answer:
The vascular tissues in the plants is a type of conducting system with the help of which the water is transported from the roots to the leaves of the plant and the vascular tissues also help in transporting the food prepared in the leaves to the various parts of the plant wherever the requirement is there.
Now we have studied the fact that the transport of water in the plants is the responsibility of the xylem. Xylem itself consists of different cells and all of them function in a coordinated manner to transport the water. The same thing is with the phloem. The phloem also consists of various cells which work together in a regulated manner in transporting the food prepared through photosynthesis in the leaves of the plant to the other parts of the plant.

Apart from the xylem and phloem, no other cells are known in transporting any kind of substance within the plant and thus our answer for the question is the Option C which is both the xylem and phloem are the examples of vascular tissue.

Note: The outer boundary of the plants is made up of the special cells known as the epidermal cells and the rigidity, structure, shape and the protection form the outside stress is the major functions of the epidermal cells. All the epidermal cells together make a layer around the plant which is known as the epidermal layer.
