Solution

The correct option is C
Supercooled liquid

Amorphous solids neither have ordered arrangement (i.e. no definite shape)
nor have sharp melting point like crystals, but when heated, they become
pliable until they assume the properties usually related to liquids. It is
therefore they are regarded as super-cooled liquids.
