Answer

To answer the question "Larva of Hydra is," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the Options
The options given are:
1. Aurelia
2. Planula
3. Tadpole
4. Hydra

### Step 2: Identify the Larva of Hydra
- **Aurelia**: This is a genus of jellyfish, and its larval stage is known as the planula. However, it is important to note that Aurelia itself is not the larva of Hydra.
- **Planula**: This is indeed a type of larva, but it is specifically associated with cnidarians like Aurelia (jellyfish) and not Hydra.
- **Tadpole**: This is the larval stage of frogs and is not related to Hydra.
- **Hydra**: This is the adult form of the organism in question, not its larva.

### Step 3: Clarify the Relationship
The video transcript indicates that the larva of Aurelia (a jellyfish) is a planula, which can develop into a hydra-like form known as hydrula. However, the question specifically asks for the larva of Hydra, which is not directly mentioned in the options.

### Step 4: Conclusion
Based on the information provided, the larva of Hydra is not explicitly listed among the options. However, it is important to note that Hydra does not have a distinct larval stage like Aurelia. Instead, Hydra reproduces asexually through budding or sexually through gametes.

### Final Answer
None of the options provided directly represent the larva of Hydra. The correct answer is that Hydra does not have a larval stage like Aurelia or Planula.
