Which of the following groups is made up of matter only? (1) Cloud, snow and wind (2) Air, thunder and water (3) Chair, sand and shadow (4) Cotton, feather and music

What you are checking in this question

A group is made up of matter only if every item in the group has mass and occupies space. Things like sound (thunder, music) and shadows are not matter.

Testing each option

• (1) Cloud, snow and wind: Cloud and snow are water droplets/ice crystals, and wind is air in motion. All are matter.
• (2) Air, thunder and water: Air and water are matter, but thunder is sound energy, not matter.
• (3) Chair, sand and shadow: Chair and sand are matter, but a shadow is the absence/blocking of light, not matter.
• (4) Cotton, feather and music: Cotton and feather are matter, but music is sound energy, not matter.

Final choice

So the only option where all three are matter is (1).
