Exocetus is able to leap into air by means of

Options

A. Large strong pectroal fins
B. Powerful tail
C. Pelvic fins
D. Suddenly flashing of dorsal and ventral fins

Answer

**Step-by-Step Solution:**

1. **Understanding Exocetus**: Exocetus, commonly known as flying fish, are unique fish that have the ability to glide above the water surface.

2. **Identifying the Mechanism**: The question asks how Exocetus is able to leap into the air. To answer this, we need to consider the anatomical features of the fish that facilitate this action.

3. **Analyzing the Options**:
- **Option 1: Large strong pectoral fins**: These fins are long and wing-like, allowing the fish to create lift and glide through the air.
- **Option 2: Powerful tail**: While the tail provides propulsion, it is not the primary mechanism for leaping into the air.
- **Option 3: Pelvic fins**: These fins do not play a significant role in leaping or gliding.
- **Option 4: Suddenly flashing of dorsal and ventral fins**: This action is not responsible for the leaping ability of Exocetus.

4. **Determining the Correct Answer**: Based on the analysis, the correct answer is **Option 1: Large strong pectoral fins**, as they are specifically adapted for gliding and enable the fish to leap into the air.

5. **Conclusion**: Therefore, Exocetus is able to leap into the air primarily due to its large, strong pectoral fins.
