Arboreal adaptation occurs in:

Options

A. Duck
B. Squirrel
C. Horse
D. Parrot.

Answer

To determine which of the given options exhibits arboreal adaptation, we can follow these steps:

### Step 1: Understand Arboreal Adaptation
Arboreal adaptation refers to the physical and behavioral traits that allow an organism to live primarily in trees. Animals with these adaptations often have features that help them climb, grasp, and navigate through a tree-dominated environment.

### Step 2: Analyze the Options
We have four options to consider:
1. Duck
2. Squirrel
3. Horse
4. Parrot

### Step 3: Evaluate Each Option
- **Duck**: Ducks are primarily aquatic birds that live in water bodies and do not spend most of their time in trees. Therefore, this option does not represent arboreal adaptation.

- **Squirrel**: While many squirrels are known to live in trees, some species are terrestrial and spend considerable time on the ground. Thus, not all squirrels can be classified as arboreal.

- **Horse**: Horses are terrestrial animals that live on land and do not have adaptations for tree living. This option is incorrect for arboreal adaptation.

- **Parrot**: Parrots are birds that are predominantly found in trees. They have adaptations such as strong feet for gripping branches and a diet that often consists of fruits and nuts found in trees. Thus, parrots are a clear example of arboreal adaptation.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Parrot** (Option D), as it is the only animal among the options that primarily lives in trees.
