The correct option is A Parenchyma, collenchyma and sclerenchyma
The ground tissue of plants is the supporting tissue which helps the specialized one to carry their function efficiently. The ground tissue includes parenchyma, sclerenchyma, and collenchyma.
Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra structural support, particularly in regions of new growth.
Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant. Ground tissue is a simple tissue. Xylem and phloem come under vascular bundles.
Thus, the correct answer is option A.
