Detailed explanation-1: -So, the correct option is ‘Monocot stem’.

Detailed explanation-2: -The vascular bundle encloses both xylem and phloem. The xylem is present in the inner surface and phloem in the outer surface and cambium is not present in monocot plants. Hence, the vascular bundles in monocot stem are endarch, closed, and collateral.

Detailed explanation-3: -Hint: Sclerenchymatous sheath-covered vascular bundles are contained in the monocot stem and they are called fibro vascular bundles. It is present in a form of eustele, in which the vascular bundles in a ground tissue are distributed or spirally arranged.

Detailed explanation-4: -In monocot stems, the hypodermis is a tightly packed layer of sclerenchyma cells located interior to the epidermis.

Detailed explanation-5: -The hypodermis is the outermost region of the cortex. In the monocot stem, the hypodermis is made up of sclerenchyma cells. The vascular bundles in the monocot stem are surrounded by sclerenchymatous bundle sheath. It is called the bundle sheath.
