E Correct answer
Explanation

Sphagnum accumulations can store water, since both living and dead plants can hold large quantities of water inside their cells, plants may hold up to 1 billion times as much water as their dry weight depending on the species. The empty cells help retain water in drier conditions. Hence, as sphagnum moss grows, it can slowly spread into drier conditions, forming larger peatlands, both raised bogs and blanket bogs.
