• B. Crystals
• C. Bacteria
• D. Metals

Answer: (C)

Verified step by step guidance

1. Understand the role of a dehydrant: A dehydrant is a substance used to remove moisture from an environment or material.
2. Recognize that moisture (water) is essential for the growth and survival of many living organisms, especially microorganisms like bacteria.
3. Identify that gases and metals do not require moisture to exist or grow, and crystals are solid structures formed by the arrangement of atoms or molecules, not living organisms.
4. Conclude that removing moisture with a dehydrant primarily helps prevent the growth of bacteria, which need water to thrive.
5. Therefore, the dehydrant's main function is to inhibit bacterial growth by eliminating the moisture they require.
