What typically happens to leaves of trees affected by Oak Wilt?

The correct choice highlights a characteristic symptom of Oak Wilt, a serious fungal disease that affects oak trees. When trees are infected with Oak Wilt, the leaves exhibit a distinct wilting behavior where the leaf edges start to turn brown and wilt inward towards the center.

This symptom is a result of the disruption of the tree's vascular system caused by the fungus, which impairs the tree’s ability to transport water. The wilting pattern is often noticeable and can progress rapidly, indicating the severity of the infection and the tree's compromised health.

While it is possible for infected trees to exhibit other symptoms such as premature leaf drop, the notable and distinctive wilting from the edges inward directly signifies the presence of the disease and is a key diagnostic feature. The other options don't accurately describe the specific impacts of Oak Wilt on leaf health or appearance as observed in infected trees.
