Deliquescent habit is shown by

Options

A. Pinus
B. Eucalyptus
C. Cocus nucifera
D. Mangifera indica

Answer

### Step-by-Step Solution:

1. **Understanding Deliquescent Habit**:
- Deliquescent habit refers to a growth pattern in plants where the branches spread out laterally in all directions. This results in a broad, dome-shaped canopy.

2. **Identifying Examples**:
- Common examples of plants exhibiting deliquescent habit include the oak tree and the mango tree (Mangifera indica). These plants have branches that grow outwards, creating a wide and rounded appearance.

3. **Analyzing the Options**:
- The question provides four options:
1. Pinus
2. Eucalyptus
3. Cocos nucifera (Coconut)
4. Mangifera indica (Mango)

4. **Evaluating Each Option**:
- **Option 1: Pinus** - This is a coniferous tree that typically has a pyramidal shape and does not exhibit a deliquescent habit.
- **Option 2: Eucalyptus** - Eucalyptus trees also do not have a deliquescent growth form; they tend to have a more columnar or straight growth.
- **Option 3: Cocos nucifera** - The coconut palm has a single trunk and does not spread its branches laterally in a dome shape.
- **Option 4: Mangifera indica** - The mango tree does exhibit a deliquescent habit, with branches spreading outwards to form a broad canopy.

5. **Conclusion**:
- After evaluating all options, the correct answer is **Option 4: Mangifera indica**.
