• C. freely, sublime, insoluble, deliquescent, anhydrous
• D. freely, decompose, soluble, hygroscopic, crystals

Answer 1

The correct option is B less, decompose, soluble, deliquescent, hydrates

A Diagonal Relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. These pairs (Li & Mg, Be & Al, B & Si etc.) exhibit similar properties.
