Which feature is a clear indicator of potential rot in hardwood timber?

• A. Conks
• B. Healthy leaf color
• C. Smooth bark
• D. Straight grain

Answer: (A)

Conks are shelf-like fruiting bodies produced by wood-decay fungi that appear on timber when rot is present or developing. Their presence is a direct sign that fungi have colonized the wood and are breaking down its structure, so the timber is likely compromised and may lack strength. Other features, like healthy leaf color, smooth bark, or straight grain, relate to living trees or wood appearance but do not reliably indicate decay inside. So conks provide a clear external clue to potential rot in hardwood timber.
