Strategy:
 Rusting is an electrochemical process. Evaluate the role of coatings, pH, and pollutants based on electrode potential and acid-base chemistry.

Step 1: Evaluate Statement (a)
Tin () is less active than Iron (). If the tin coating is scratched (peeled off), Iron becomes the anode and undergoes sacrificial corrosion even faster than without the tin. Thus, tin only protects iron while the coating is perfectly intact.

Step 2: Evaluate other statements
- (b): In alkaline conditions (), th
