The answer is the second one: Anhydrobiosis.

Explanation for each option:

  • Guttation: This is a process in plants where water is expelled from the tips of leaves, not related to dormancy in organisms like tardigrades.

  • Anhydrobiosis: This is the correct answer. It is a biological condition where an organism loses most of its water content and enters a state of dormancy to survive extreme desiccation. Tardigrades are known for undergoing anhydrobiosis.

  • Hibernation: This is a state of inactivity and metabolic depression in endotherms, typically associated with cold temperatures, not related to water loss.

  • Estivation: This is a state of dormancy similar to hibernation but occurs in response to high temperatures and arid conditions, not specifically related to water loss.

In summary, the condition described in the question is anhydrobiosis, which is observed in tardigrades.
