The interactions between dwarf mistletoe and trees are best described as parasitic.
Option B is correct.
A witches broom, a structure produced by some dwarf mistletoe species, interrupts the regular branching structure and causes abnormal tree development where it infects the tree. Dwarf mistletoes are diminutive, leafless parasitic blooming plants that progressively starve trees of nutrients and water, killing them.
The virtually leafless shoots can be any color, although the most frequent ones are yellow, brown, purple, or green. The size of plants also differs across and within species. Dwarf mistletoe shoots from Douglas-fir are frequently shorter than the host's leaves, whereas those from the Southwest are typically 3–6 inches (7–15 cm) long.
