Solution

The correct option is C X - Gold
Y - Glass
Malleability is the property due to which metals can be hammered into thin sheets without breaking.

Brittleness is the property due to which a substance is broken down into small pieces when pressure is applied.

So, X should be a malleable substance and Y should be a brittle substance.

Glass and chalk are brittle. Gold and copper are malleable. So, from the given options, X should be gold and Y should be glass.
