The correct answer is D. Water.
The question is a simile, which is a comparison of two unlike things using the words “like” or “as.” In this case, the tiger is being compared to the forest, and the otter is being
compared to something else. The answer must be something that is closely associated with otters, just as the forest is closely associated with tigers.Option A, cage, is incorrect because otters are not typically found in cages. They are wild animals that live in the water.
Option B, sky, is incorrect because otters do not typically live in the sky. They are aquatic animals that live in the water.
Option C, nest, is incorrect because otters do not typically build nests. They give birth to their young in dens, which can be found in burrows, caves, or hollow logs.
Option D, water, is the correct answer because otters are aquatic animals that live in the water. They are excellent swimmers and divers, and they spend most of their time in the water. They eat fish, frogs, crayfish, and other aquatic animals.
