Preventing iron corrosion is important because many structures, including bridges and iron railings, are likely to rust over time and become weaker. which of the following conditions would make corrosion more likely?
a. increasing the moisture level near the structure
b. reducing the concentration of electrolytes in solutions in contact with the structure
c. neutralizing any acidic solutions near the iron
d. painting the iron surface

D. painting the iron surface

Explanation:

Iron gets oxidized in the presence of oxygen and moisture to form iron oxide. This iron oxide is red in color and is known as rust.  

Option D is correct. Painting the iron surface is effective in reducing its corrosion. For example when iron is coated with zinc, the zinc is more likely to get oxidized first than the underlying iron.  

Option A is incorrect. Increasing the moisture level will facilitate the rusting of iron.  

Option B and C are incorrect as rusting is not affected by acids of electrolytes in solutions.
