Options

A. Vanda
B. Arachis
C. Cuscuta
D. Taeniophyllum

Answer

To answer the question "Chlorophyllous, autotrophic aerial roots are seen in," we can follow these steps:

### Step 1: Understand the Terms
- **Chlorophyllous**: This refers to roots that contain chlorophyll, which is the pigment necessary for photosynthesis.
- **Autotrophic**: This means that the organism can synthesize its own food from simple inorganic substances, primarily through the process of photosynthesis.
- **Aerial Roots**: These are roots that grow above the ground and are often exposed to air.

### Step 2: Analyze the Options
We have four options to consider:
- A. Venda
- B. Regis
- C. Cascata
- D. Tenuophyllum

### Step 3: Identify the Characteristics
We need to find which of these options has roots that are:
1. Chlorophyllous (contain chlorophyll)
2. Autotrophic (can perform photosynthesis)
3. Aerial (growing above ground)

### Step 4: Evaluate Each Option
- **Venda**: Not known for chlorophyllous aerial roots.
- **Regis**: Also does not typically have these types of roots.
- **Cascata**: Similar to the previous two, it does not fit the criteria.
- **Tenuophyllum**: This plant belongs to the Orchid family, has short stems, and possesses flat, green, photosynthetic roots that are aerial.

### Step 5: Conclusion
Based on the analysis, the correct answer is:
**D. Tenuophyllum**
