Detailed explanation-1: -So, the correct answer is ‘Complex tissues’.

Detailed explanation-2: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves. Xylem is responsible for the transport of water and dissolved ions from the roots upwards through the plant.

Detailed explanation-3: -Xylem & Phloem are called complex tissues. Both xylem and phloem have atleast 4 different components having different kind of tissues that make them up. Due to this complexity of the tissue, they are classified as complex tissues.

Detailed explanation-4: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-5: -Xylem and phloem are called vascular or conducting tissues because both xylem and phloem tissues transport materials in plants, they are together called vascular tissues.
