Question

____ is an indispensable substance for all living things.

○ pizza

○ clothes

○ water

○ snow

Explanation:

To solve this, we analyze each option:

• Pizza is food, not a substance essential for all living things' basic survival.
• Clothes are a human - made item for protection, not essential for all living organisms.
• Water is essential for all living things as it is involved in many biological processes like metabolism, transportation of nutrients, etc.
• Snow is a form of water in solid state, but not the essential substance itself in the general sense for all living things (many organisms don't interact with snow directly for survival).

Answer:

C. Water
