Which consequence results when the lead sheathing on a wooden ship's hull experiences prolonged immersion in seawater?

💡 Explanation

When lead sheathing is immersed in seawater, galvanic corrosion occurs because lead is anodic to other metals present (iron fittings), establishing an electrochemical cell that corrodes the lead and accelerates wood rot beneath. Therefore, galvanic corrosion results, rather than barnacle adhesion, instability, or combustion, which require different environmental triggers.
