Hint:
Ground tissue is the tissue found between the epidermis and vascular tissues. The tissue that has concentric layers found in the stem of flowering plants in which the seeds are made up of two embryonic leaves. It can be found in the species of Cucurbita or sunflower. Open vascular bundles can be observed.

Complete answer:
Ground tissue having differentiated concentric layers is found in a dicot stem.
The ground tissue of a dicot stem is made up of cortex which is differentiated to form hypodermis, general cortex, and endodermis.
The ground tissue of a plant is a type of tissue that is neither dermal or vascular. The cells that make up ground tissue are parenchyma, sclerenchyma, and collenchyma.
The parenchyma cells have thin walls and have various functions as storage, secretions, and photosynthesis.
Sclerenchyma and collenchyma have thick walls and their function is to provide structural support to the plant.
DICOT LEAF - The ground tissue of a dicot leaf is made up of mesophyll that differentiates into palisade and spongy parenchyma.

MONOCOT LEAF - The ground tissue of a monocot leaf is also made up of mesophyll, however, there is no differentiation.

MONOCOT STEM - The ground tissue of a monocot stem is present on the inner side of the hypodermis and it shows a scattered arrangement of the vascular bundles.

The correct answer is option (C) Dicot stem.

Note: A dicot stem is generally solid.
The hypodermis of a dicot stem, which is made up of collenchyma, provides mechanical support to the plant.
The endodermis is also called starch sheath as a large number of starch grains are present in the cells.
