A
Crystal of iodine
B
Lump of sulphur
C
Piece of coal
D
Zinc granule
Solution:
Zinc granules will be flattened by beating with a hammer. The property of metals being flattened on beating with a hammer is known as malleability. It is only found in metals. Zinc granules fall in this category. Iodine and Sulphur are non-metal; it is very soft, and they will break into powdered form if little force is applied. A piece of coal will get broken if it does not have malleable property.
