Which organism is catalase positive and forms V forms among Gram-positive bacteria?

V-shaped cell arrangements are a telltale feature of certain Gram-positive rods that divide in a snapping fashion, producing paired cells that align in V or palisade-like patterns. Among Gram-positive bacteria, those that are catalase positive and show these V forms are Propionibacterium species and Corynebacterium species. This combination—catalase positivity plus the characteristic V-shaped/palisading arrangement—points to these organisms. In contrast, Nocardia tends to form branching, filamentous structures and is not restricted to V shapes, and the other two options are Gram-negative, not fitting the description. So the organism described is Propionibacterium or Corynebacterium because of the catalase activity and the distinctive V-shaped cell arrangement.
