Hint: Non-porous wood occurs in plants that lack the ability to flower. Such flowers lack vessel pores in them, which makes them non-porous in nature. Example; Pine.

Complete answer:
The wood of angiosperms includes vessels, which is known as porous wood. On the other hand, vessels are absent in the wood of gymnosperms and it is known as nonporous wood. Gymnosperms are contemplated as 'non-porous' due to their scarcity of vessel pores. Pines are typical instances of softwood. So, non-porous wood originates in gymnosperms. The dicotyledons, also known as dicots, are one of the two groups into which all the flowering plants, also known as angiosperms were formerly divided. The name implies that the seed has two embryonic leaves or cotyledons. Monocotyledons also referred to as monocots, are grass and grass-like flowering plants known as angiosperms. The seeds in monocots generally comprise only one embryonic leaf or cotyledon. The gymnosperms also known as acro gymnospermae, are the group of seed-producing plants which contain conifers, cycads, Ginkgo, as well as gnetophytes. The term "gymnosperm" comes from the blended word in Greek meaning "naked seeds". The name is founded on the unenclosed situation of their seeds. A cactus is a unit of the plant family Cactaceae, a family including about 127 genera with some 1750 known species of the order Caryophyllales.
Hence, the correct answer is Option (C).

Note: The citing to wood, most softwoods, like pine, cedar and redwood, are non-porous. The non-porous woods do not possess many vessels within the wood fibres. The cells in it are typically smaller, as well as the grain of the wood is wide and open.
