B - Protoderm - Epidermis
The protoderm is the primary meristem responsible for the formation of the epidermis, which is the outermost layer of cells in plant organs such as stems, leaves, and roots. The procambium, on the other hand, gives rise to the vascular tissue, which includes the xylem and phloem, while the ground tissue arises from the ground meristem. Therefore, options A, C, D, and E are incorrect.
