By shedding their outer layers or shells


Option: 4

By rapidly returning to their normal level of activity and function

Correct option (a)

When abiotic causes, such as dehydration or freezing temperatures, cause an organism to pause its metabolism, it usually resumes when the situation improves by gradually boosting its metabolic rate. The terms "reanimation" and "rehydration" describe this process.

The organism's metabolic functions slow down during suspension, enabling it to store energy and endure in a dormant state. The organism's tissues and organs may amass waste or sustain damage as a result of this, which also signifies that they are not operating normally.

The organism must gradually ramp up its metabolic activity to repair any damage, remove waste products, and resume normal functioning when the situation improves, it is rehydrated, or it returns to a more favorable environment.

 The organism can adapt to the shifting environmental conditions and prevent further stress or harm thanks to this progressive increase in metabolic rate. An organism could be at risk of shock or other issues if it suddenly resumed its normal level of activity and function after a period of suspension. 

Therefore, the organism's ability to survive and recover depends on the slow, progressive process of boosting metabolic rate over time.

Option a is the correct answer.
