Options

A. Sycon
B. Spongilla
C. Hydra
D. Both (1) & (3)

Answer

To answer the question "External budding is present in," we will follow these steps:

### Step 1: Understand the Concept of Budding
Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. There are two types of budding:
- **External Budding (Exogenous Budding)**: The bud develops on the surface of the parent organism and eventually detaches.
- **Internal Budding (Endogenous Budding)**: The bud develops inside the parent organism's cells.

### Step 2: Identify the Organisms in the Options
The question provides four options:
1. Cyclone
2. Spondyla
3. Hydra
4. Both 1 and 3 (Cyclone and Hydra)

### Step 3: Analyze Each Option
- **Cyclone**: Known to reproduce through external budding.
- **Spondyla**: Known for internal budding.
- **Hydra**: Also reproduces through external budding.

### Step 4: Determine the Correct Answer
Since both Cyclone and Hydra exhibit external budding, the correct answer is:
- **Both 1 and 3 (Cyclone and Hydra)**.

### Final Answer
External budding is present in **both Cyclone and Hydra**.
