Solution

Pure aluminium is a silvery-white metal. Option \(A\) is correct.
Aluminium alloys are alloys in which aluminium (\(Al\)) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, etc. Therefore, option \(B\) is correct.
The use of aluminium and its compounds for domestic purposes is now increased considerably statement is incorrect.
