Metals exists as solids at room temperature but Gallium and mercury are  liquid metals.
They Exists as liquids at room temparature.
Hence option C is correct.

The density of non metals isl ow when compared with  metals as metals are solids and non metals are liquids and gases(Generally solids are more denser than liquids and gases).
Hence option C is correct.

The density of  metals are high when compared with  non metals as metals are solids and non metals are liquids and gases(Generally solids are more denser than liquids and gases).
Hence option A is correct.

Non-metals are generally solids and gases. They do not exist as liquids except Bromine. Bromine is a liquid non-metal.

Generally Non metals are not lustrous(not shiny). But Iodine is the only non metal which is lustrous. Iodine is shiny. Hence, option A is correct.

Metal oxides are basic in nature whereas non-metal oxides are acidic in nature.

Non-metals are not sonorous as they do not produce sound when they are beaten. 

Metal oxides forms bases and non metal oxides forms acids when they react with water. Metal oxides when they reacted with water it produces bases. Hence, option A is correct.
