In which of the following, scientific name, family and common name are correctly mentioned ?

Options

A. `{:(" Scientific name Family Common name"),("Batrachospermum Rhodohyceae Frog's spawn algae"):}`
B. `{:("Scientific name Family Common name"),("Spirogyra Chlorophyceae Water net"):}`
C. `{:("Scientific name Family Common name"),("Lycopodium Lycopodiaceae Sanjeevani"):}`
D. `{:("Scientific name Family Common name"),("Selaginella Lycopodiaceae Little club moss"):}`

Answer

To solve the question regarding the correct matching of scientific name, family, and common name, we will follow these steps:

### Step 1: Understand the Components
The scientific name consists of two parts: the genus name and the species name. The genus name is capitalized, while the species name is in lowercase. Both names are italicized.

### Step 2: Analyze the Given Options
We have several options to evaluate:
1. **Batrachospermum** - Family: **Rhodophyceae** - Common Name: **Frogspan**
2. **Spirogyra** - Family: **Chlorophyceae** - Common Name: **Waternet**
3. **Lycopodium** - Family: **Lycopodiaceae** - Common Name: **Sanchevium**
4. **Selaginella** - Family: **Lycopodiaceae** - Common Name: **Little Clubmoss**

### Step 3: Verify Each Option
- **Option 1**: Batrachospermum is indeed a red algae, but it belongs to the family **Rhodophyceae**, not **Rhodosai**. The common name "Frogspan" is not widely recognized.

- **Option 2**: Spirogyra belongs to the family **Chlorophyceae**, and "Waternet" is a common name used for it. This option seems correct.

- **Option 3**: Lycopodium belongs to the family **Lycopodiaceae**, but "Sanchevium" is not a recognized common name for it.

- **Option 4**: Selaginella is a member of the family **Selaginellaceae**, not **Lycopodiaceae**, and "Little Clubmoss" is not a correct common name for it.

### Step 4: Identify the Correct Option
From the analysis, **Option 2** (Spirogyra - Chlorophyceae - Waternet) is the only option where the scientific name, family, and common name are correctly matched.

### Final Answer
The correct answer is **Option 2: Spirogyra - Chlorophyceae - Waternet**.
