Algae with multinucleate, haploid condition is
(A) Mucor (B) Vaucheria
(C) Spirogyra (D) Rhizopus

Options

A. A, B
B. B, C
C. B
D. C, D

Answer

To solve the question "Algae with multinucleate, haploid condition is", we need to analyze the options provided:

1. **Understanding the Terms**:
- **Multinucleate**: This means that the cell contains multiple nuclei.
- **Haploid**: This refers to a cell that has a single set of unpaired chromosomes, denoted as 'n'.

2. **Analyzing the Options**:
- **(A) Mucor**: This is a genus of fungi, not algae.
- **(B) Vaucheria**: This is a type of green algae that is known to have a multinucleate condition and is haploid.
- **(C) Spirogyra**: This is also a green algae, but it typically has a filamentous structure and is not multinucleate in the same way as Vaucheria.
- **(D) Rhizopus**: This is another genus of fungi, not algae.

3. **Identifying the Correct Answer**:
- From the analysis, Vaucheria is the only option that fits the criteria of being a multinucleate, haploid algae.
- Spirogyra, while being an algae, does not have a multinucleate condition.

Thus, the correct answer is **(B) Vaucheria**.
