Solution

The correct option is B Pycnoxylic
In Pinus, pycnoxylic wood is present. It is formed in more than one ring due to ephemeral nature of cambium. Such a wood is called as polyxylic. Cambial activity is long-lived, cortex and pith are reduced, parenchymatous rays are few, wood is hard and compact, wood is commercially most important and used as good quality timber.
