D. XXX

Answer

To solve the question regarding the webbed neck condition, we need to understand the genetic basis of the condition and the options provided.

### Step-by-Step Solution:

1. **Understanding Webbed Neck Condition**:
- The webbed neck condition is a characteristic associated with Turner’s syndrome. This syndrome is a genetic disorder that affects females and is caused by the absence of one of the X chromosomes.

2. **Identifying Turner’s Syndrome**:
- Turner’s syndrome is characterized by a 45, X karyotype, meaning that there is a total of 45 chromosomes instead of the usual 46. Specifically, it involves having only one X chromosome (X0) instead of two (XX).

3. **Analyzing the Options**:
- **Option A: X X Y** - This represents a male with an extra Y chromosome, not Turner’s syndrome.
- **Option B: X Y** - This represents a normal male karyotype, not associated with Turner’s syndrome.
- **Option C: X O** - This represents Turner’s syndrome (monosomy X), which is characterized by the webbed neck condition.
- **Option D: X X X** - This represents a female with an extra X chromosome, known as Triple X syndrome, not Turner’s syndrome.

4. **Conclusion**:
- The only option that corresponds to the webbed neck condition is **Option C: X O**.

### Final Answer:
The webbed neck condition will be observed in **Option C: X O**.
