Genomic nucleic acid is fragmented in
(a) TMV
(b) Influenza virus
(c) HIV
(d) Poliomyelitis virus.

Options

A. TMV
B. Influenza virus
C. HIV
D. Poliomyelitis virus.

Answer

To determine which virus has fragmented genomic nucleic acid, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which of the listed viruses has fragmented genomic nucleic acid. Fragmented nucleic acid means that the genetic material is divided into segments rather than being a single continuous strand.

2. **Analyzing TMV (Tobacco Mosaic Virus)**:
- TMV is a plant virus that contains single-stranded RNA.
- The RNA in TMV is unfragmented or unsegmented.
- **Conclusion**: TMV does not have fragmented genomic nucleic acid.

3. **Analyzing Influenza Virus**:
- Influenza virus is known for having a segmented genome.
- It possesses segmented negative-strand RNA.
- **Conclusion**: Influenza virus has fragmented genomic nucleic acid.

4. **Analyzing HIV (Human Immunodeficiency Virus)**:
- HIV is an RNA virus that contains two copies of single-stranded RNA.
- The RNA in HIV is unfragmented.
- **Conclusion**: HIV does not have fragmented genomic nucleic acid.

5. **Analyzing Poliomyelitis Virus**:
- Poliomyelitis virus is a causative agent of polio and has single-stranded positive-sense RNA.
- The RNA in poliomyelitis virus is also unfragmented.
- **Conclusion**: Poliomyelitis virus does not have fragmented genomic nucleic acid.

6. **Final Conclusion**: Based on the analysis, the only virus from the options provided that has fragmented genomic nucleic acid is **(b) Influenza virus**.

### Final Answer:
(b) Influenza virus
