Larch is unusual among conifers because it is deciduous, dropping its needles each autumn. Most conifers like cedar, spruce, and pine retain their leaves year-round as evergreens.

If all trees in the park are flowering trees, and dogwoods are trees in the park, then those dogwoods must be flowering trees. This is a valid syllogism: All P are Q; Some R are P; Therefore, those R that are P must be Q. The third statement follows necessarily from the first two.

Xyloid is an adjective meaning 'of, relating to, resembling wood' or 'having the characteristics of wood' (from Greek xulon = wood). Option C 'like wood' correctly defines this term.
