Aluminium is resistant to corrosion primarily because:
Correct: B
Aluminium is a highly reactive metal, but it exhibits excellent corrosion resistance due to the formation of a very thin, dense, and tenacious layer of aluminium oxide (Al2O3) on its surface when exposed to air. This passive oxide layer prevents further oxidation of the underlying metal, effectively protecting it from corrosion. This process is often enhanced artificially through anodizing.
