Hint: Knowing intermolecular force between atoms of metal is stronger is must. Also physical and chemical properties of solids, metals should be considered. Exceptions in chemistry should be kept in mind.
Complete answer:
At room temperature, metals are present in solid state. Thus physical property metals are like solids.
Solids have a very strong intermolecular force of attraction, thus the interstitial space between the corresponding atoms are too low. This helps them to acquire a definite shape and volume.
Metals also have high density, and because of strong forces they possess high melting point also. They have luster, are good conductors of heat and electricity. They are used in kitchen appliances, household appliances, and electrical appliances. Also many alloys (mixtures of metals and non-metals) are used in kitchen and household appliances.
Most of the metals are hard but there are some exceptions, like Sodium (\[Na\]) and Potassium ($K$) are soft and can be cut with a knife. They are also highly reactive metals as when they come in contact with air they react vigorously and catch fire.so they are kept in kerosene.
Metals can be drawn into thin wires and thin sheets. Thus they are also ductile and malleable.
Metals like Tungsten ( $W$), Iridium ($Ir$) and Titanium ($Ti$) are some of the hardest metals.
Hence option (B) is correct.
Note: Proper knowledge about physical and chemicals properties of metals is necessary. There are certain exceptions in the metal family which should also be considered when answering these questions. One exception among the metals is Mercury ($Hg$), as at room temperature it exists in liquid form.
