Match the following columns
`{:("","Column-I","","Column-II"),(A,"Logistic growth",1,"Sigmoid growth"),(B,"Expnentuial growth",2,"Verhulst-pearl logistic growth"),("","",3,"Geometic growth"),("","",4,"J-shaped growth"):}`

Options

A. A-1 and 2, B-3,4
B. A-,4B-1 and 2
C. A-1,3 and 4 ,B-2
D. A-1,B-2,3 and 4

Answer

To solve the question of matching the columns, we need to analyze the terms in Column-I and Column-II and identify the correct pairs based on their definitions and characteristics.

### Step-by-Step Solution:

1. **Identify the Terms in Column-I:**
- A: Logistic growth
- B: Exponential growth

2. **Understand Logistic Growth:**
- Logistic growth occurs when resources are limited.
- It is characterized by an S-shaped curve, also known as sigmoid growth.
- This type of growth is described by the Verhulst-Pearl logistic model.

3. **Match Logistic Growth:**
- From the understanding above, we can match:
- A (Logistic growth) with 1 (Sigmoid growth) and 2 (Verhulst-Pearl logistic growth).
- Therefore, A matches with 1 and 2.

4. **Understand Exponential Growth:**
- Exponential growth occurs when resources are unlimited.
- It is characterized by a J-shaped curve.
- This type of growth is also referred to as geometric growth.

5. **Match Exponential Growth:**
- From the understanding above, we can match:
- B (Exponential growth) with 3 (Geometric growth) and 4 (J-shaped growth).
- Therefore, B matches with 3 and 4.

6. **Combine the Matches:**
- Now we have:
- A matches with 1 and 2.
- B matches with 3 and 4.
- The correct combination is found in option 1.

7. **Final Answer:**
- The correct answer is option 1, which matches the pairs as follows:
- A (Logistic growth) → 1 (Sigmoid growth) and 2 (Verhulst-Pearl logistic growth)
- B (Exponential growth) → 3 (Geometric growth) and 4 (J-shaped growth)
