A. Orchid
B. Margosa
C. Mustard
D. Mango

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which plant absorbs water from the atmosphere. This indicates we are looking for a plant that can take moisture from the air rather than solely from the soil.

2. **Identifying the Options**: The options provided are orchid, margosa, mustard, and mango. We need to analyze which of these plants has the ability to absorb moisture from the atmosphere.

3. **Defining Areal Roots**: Areal roots are specialized roots that grow above the ground and are capable of absorbing moisture from the air. These roots are typically found in certain types of plants known as epiphytes.

4. **Understanding Epiphytes**: Epiphytes are plants that grow on other plants but do not take nutrients from them. Instead, they absorb moisture and nutrients from the air and surrounding organic debris.

5. **Identifying the Correct Plant**: Among the options, orchids are known to be epiphytes. They have areal roots that can absorb moisture from the humid air, thanks to a specialized spongy layer in their epidermis called vellum.

6. **Conclusion**: Based on the characteristics of the plants listed, the correct answer is **orchid**, as it has the ability to absorb water from the atmosphere through its areal roots.

**Final Answer**: Orchid
