Answer 2

Hi My Dear Friend!

Answer: Option (C)pure water .

Explanation: Air is a mixture of gases as it contains dust, water vapour, various types of gases (carbon dioxide, oxygen, nitrogen and etc) so it will not be option (A). Seawater is a mixture as it contains water and salt and sometimes dusts too so it also not be Option (B). Soil is a mixture as it contains dust, water vapour, air, water and etc so it will not be Option (D) too. Pure water is not a mixture as the word ''PURE'' gives us an idea that the water is clean and contains no materials except water so therefore the answer is Option (C).
