Show answer and explanation

Correct answer: (B) Fly-ash bricks < MDF < Float glass < Aluminium

Explanation

The specified order is fly-ash bricks, medium-density fibreboard, float glass, aluminium, B. Primary aluminium production is especially energy-intensive; glass melting also requires substantial process heat. The comparison is the source’s material-basis ordering, not a claim that equal-volume finished assemblies always follow the same energy ranking.
