Options

A. Ficus cairica
B. Yucca
C. Tagetes
D. Cosmos.

Answer

To solve the question regarding which plant is pollinated by the moth Pronuba (also known as Tegaticula) and where it passes its larval stage, we can follow these steps:

### Step 1: Understand the Relationship
The moth Pronuba has a specific relationship with a plant where it not only pollinates the plant but also lays its larvae in it. This indicates a mutualistic relationship, where both the moth and the plant benefit from each other.

**Hint:** Look for plants that have a known mutualistic relationship with specific moths.

### Step 2: Identify the Moth
The moth in question is known as the "yucca moth." This name suggests a strong connection to the yucca plant. The yucca moth is specifically adapted to pollinate yucca plants.

**Hint:** Consider the name of the moth and its association with particular plants.

### Step 3: Analyze the Options
Now, let's analyze the options provided:
- **Option A: Ficus canica** - This plant is not known to have a relationship with the yucca moth.
- **Option B: Yucca** - This is the plant that the yucca moth pollinates and where it lays its larvae.
- **Option C: Tagetes** - This plant does not have a known relationship with the yucca moth.
- **Option D: Cosmos** - Similar to Tagetes, Cosmos does not have a mutualistic relationship with the yucca moth.

**Hint:** Eliminate options that do not have a known relationship with the moth.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Option B: Yucca**. The moth Pronuba (yucca moth) pollinates the yucca plant and lays its larvae in it, demonstrating a mutualistic relationship.

**Final Answer:** The plant is **Yucca**.
