Arrange the following in ascending manner basing on their life span
(a) Carrot (b) Wolffia (c ) Rosa plant (d) Pinus plant

Options

A. a,b,c,d
B. a,b,d,c
C. b,a,d,c
D. b,a,c,d

Answer

To arrange the given organisms based on their lifespan in ascending order, we will analyze each organism's lifespan:

1. **Wolffia (Duckweed)**: This is known as the smallest flowering plant on Earth. It has a very short lifespan of about **14 days**.

2. **Carrot (Daucus carota)**: The carrot is a root vegetable that typically has a lifespan of about **2 years**.

3. **Rosa Plant (Rose)**: The lifespan of rose plants generally ranges from **5 to 7 years**.

4. **Pinus Plant (Pine)**: Pine trees can have an extensive lifespan, living anywhere from **100 to 1,000 years** or even longer.

Now, we will arrange these organisms in ascending order based on their lifespan:

- **Wolffia**: 14 days
- **Carrot**: 2 years
- **Rosa Plant**: 5 to 7 years
- **Pinus Plant**: 100 to 1,000 years

Thus, the ascending order of lifespan is:

1. **Wolffia** (14 days)
2. **Carrot** (2 years)
3. **Rosa Plant** (5 to 7 years)
4. **Pinus Plant** (100 to 1,000 years)

### Final Arrangement in Ascending Order:
- **Wolffia (b)**
- **Carrot (a)**
- **Rosa Plant (c)**
- **Pinus Plant (d)**

### Answer:
**(b) Wolffia < (a) Carrot < (c) Rosa Plant < (d) Pinus Plant**
