In general, viruses that infect plants have …………

Options

A. dsDNA
B. dsRNA
C. ssDNA
D. ssRNA

Answer

To solve the question regarding the type of genetic material that viruses infecting plants generally possess, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the general type of genetic material found in viruses that infect plants.

2. **Analyze the Options**:
- **Option 1: Double Stranded DNA**: This option is incorrect as most plant viruses do not have double-stranded DNA.
- **Option 2: Double Stranded RNA**: This option is also incorrect; while some viruses have double-stranded RNA, they are not the most common type that infects plants.
- **Option 3: Single Stranded DNA**: This option is incorrect as well; single-stranded DNA viruses are not typical among plant viruses.
- **Option 4: Single Stranded RNA**: This is the correct option. Most plant viruses are known to have single-stranded RNA as their genetic material.

3. **Conclusion**: Based on the analysis of the options, the correct answer is that viruses that infect plants generally have single-stranded RNA.

### Final Answer:
In general, viruses that infect plants have **single-stranded RNA**.
