Which outcome results at the interface when differential oxygen concentrations sustain microbiologically induced corrosion of steel submerged in seawater?

A)Increased chloride ion transport
B)Uniform passivation layer formation
C)Elevated cathodic protection current
D)Decreased biofilm attachment strength

💡 Explanation

Increased chloride ion transport occurs because *ionic* transport is enhanced by increased surface charge density during differential aeration; the increased concentration of hydroxyl ions generates a charge, leading to *ionic* migration; therefore increased local breakdown, rather than uniform protection occurs.
