E Correct answer
Explanation

Pine trees are susceptible to pine pitch canker. Pine pitch canker first kills the tips of branches, then spreads down entire branches, and ultimately it can kill the whole tree. Infected trees die because the fungus thrives inside the tree's vascular tissue and blocks its water supply. The fungus is spread through the beetles that attack the pine cones.
