The provided reference describes bacterial spores and the cell that produces them, which is called a vegetative cell. A vegetative cell is the metabolically active and growing form of a bacterial cell, as opposed to a spore. The reference doesn't define "vegetative spores." It describes bacterial spores as a resistant structure to unfavorable environmental conditions. Each cell produces only one spore and each spore germinates to one vegetative cell.
Because the term "vegetative spore" is not used in the reference, it is possible the question is unclear or using non-standard terminology. The reference only describes bacterial spores and vegetative cells.
