All the options, A. a frog, B. all of the above, C. sand, and D. water, are made of matter.
Step-by-step explanation:
1. A Frog (Option A): Living organisms, including frogs, are composed of matter. Frogs are made up of various elements and compounds, constituting biological matter.
2. All of the Above (Option B): This option includes a frog (biological matter), sand (composed of minerals, which are matter), and water (composed of molecules, also matter). Therefore, this option encompasses different forms of matter.
3. Sand (Option C): Sand is composed of tiny mineral particles, and minerals are definite forms of matter with mass and volume.
4. Water (Option D): Water is a compound made up of molecules (H₂O), and both the molecules and the compound itself are forms of matter.
In summary, all the options listed—whether living organisms like frogs or inanimate substances like sand and water—are composed of matter.
