Which of the following is the largest -

Options

A. Whale
B. Giant tortoise
C. Hippopotamus
D. Elephant

Answer

To determine which of the given organisms is the largest, we need to compare their dimensions, including length, height, and weight. Here’s a step-by-step breakdown:

### Step 1: Identify the Organisms and Their Dimensions
We have four organisms to compare:
1. **Elephant**
- Length: 5.5 to 6.5 meters
- Height: 2.8 to 3.2 meters
- Weight: 2700 to 4000 kg

2. **Hippopotamus**
- Length: 2.9 to 4.3 meters
- Height: 1.5 to 2 meters
- Weight: 1500 to 1800 kg

3. **Giant Tortoise**
- Length: 1.22 to 1.52 meters
- Height: 0.16 to 0.91 meters
- Weight: 150 to 250 kg

4. **Blue Whale**
- Length: 25 to 32 meters
- Height: 3.96 to 4.88 meters
- Weight: 55,000 to 165,000 kg (55 to 165 tons)

### Step 2: Compare the Lengths
- **Elephant**: 5.5 to 6.5 meters
- **Hippopotamus**: 2.9 to 4.3 meters
- **Giant Tortoise**: 1.22 to 1.52 meters
- **Blue Whale**: 25 to 32 meters

From this comparison, the **Blue Whale** is significantly longer than the other three organisms.

### Step 3: Compare the Heights
- **Elephant**: 2.8 to 3.2 meters
- **Hippopotamus**: 1.5 to 2 meters
- **Giant Tortoise**: 0.16 to 0.91 meters
- **Blue Whale**: 3.96 to 4.88 meters

Again, the **Blue Whale** has the greatest height.

### Step 4: Compare the Weights
- **Elephant**: 2700 to 4000 kg
- **Hippopotamus**: 1500 to 1800 kg
- **Giant Tortoise**: 150 to 250 kg
- **Blue Whale**: 55,000 to 165,000 kg

The **Blue Whale** also outweighs all the other organisms by a large margin.

### Conclusion
After comparing the dimensions (length, height, and weight) of all four organisms, it is clear that the **Blue Whale** is the largest organism among the options provided.
