Select the option which arranges the given organisms in ascending order of their life span.

Options

A. `"Parrot " lt "Crow " lt " Butterfly " lt "Banyan tree"`
B. `"Butterfly " lt "Crow" lt" Parrot " lt "Crocodile"`
C. `"Fruit fly " lt "Crocodile " lt " Parrot " lt "Banyan tree"`
D. `"Parrot " lt "Tortoise" lt " Dog " lt "Crow"`

Answer

To solve the question of arranging the given organisms in ascending order of their lifespan, we need to first identify the lifespan of each organism mentioned. Here’s a step-by-step breakdown:

### Step 1: Identify Lifespan of Each Organism
1. **Butterfly**: Lives for about **1 month** (approximately **30 days**).
2. **Fruit Fly**: Lives for about **50 days**.
3. **Dog**: Lives for about **10 to 13 years**.
4. **Crow**: Lives for about **20 years**.
5. **Crocodile**: Lives for about **70 years**.
6. **Parrot**: Lives for about **140 years**.
7. **Tortoise**: Lives for about **200 years**.
8. **Banyan Tree**: Lives for about **200 to 300 years**.

### Step 2: Convert All Lifespans to the Same Unit
To make comparisons easier, we can convert all lifespans into years:
- Butterfly: 1 month = 1/12 years (approximately 0.083 years)
- Fruit Fly: 50 days = 50/365 years (approximately 0.137 years)
- Dog: 10 to 13 years (let's take the average, about 11.5 years)
- Crow: 20 years
- Crocodile: 70 years
- Parrot: 140 years
- Tortoise: 200 years
- Banyan Tree: 200 to 300 years (let's take the average, about 250 years)

### Step 3: List Lifespans in Ascending Order
Now we can list the organisms based on their lifespan:
1. **Butterfly**: 0.083 years
2. **Fruit Fly**: 0.137 years
3. **Dog**: 11.5 years
4. **Crow**: 20 years
5. **Crocodile**: 70 years
6. **Parrot**: 140 years
7. **Tortoise**: 200 years
8. **Banyan Tree**: 250 years

### Step 4: Final Arrangement
Based on the above calculations, the organisms arranged in ascending order of their lifespan are:
1. Butterfly
2. Fruit Fly
3. Dog
4. Crow
5. Crocodile
6. Parrot
7. Tortoise
8. Banyan Tree

### Step 5: Select the Correct Option
From the options provided, we need to select the one that matches our ascending order. The correct option is the one that lists:
- Butterfly, Fruit Fly, Dog, Crow, Crocodile, Parrot, Tortoise, Banyan Tree.
