D. Super female

Answer

To solve the question "A person with chromosome complement of XXX is," we will analyze the options provided and determine which one corresponds to the XXX chromosome complement.

### Step-by-Step Solution:

1. **Understanding the Chromosome Complement**:
- The chromosome complement of XXX indicates that there are three X chromosomes present. This is a specific chromosomal arrangement that can lead to certain syndromes.

2. **Analyzing the Options**:
- **Option A: Klinefelter Syndrome**:
- Klinefelter syndrome occurs in males who have an extra X chromosome, resulting in a chromosome complement of XXY. Therefore, this option is incorrect for XXX.

- **Option B: Down Syndrome**:
- Down syndrome is caused by trisomy of chromosome 21, which means there is an extra copy of the 21st chromosome (47 chromosomes total, with 3 copies of chromosome 21). This is unrelated to the sex chromosomes and thus incorrect for XXX.

- **Option C: Turner Syndrome**:
- Turner syndrome occurs in females who have only one X chromosome (45 chromosomes total, with a chromosome complement of X0). This means one X chromosome is missing, making this option incorrect for XXX.

- **Option D: Super Female**:
- The term "super female" refers to individuals with an XXX chromosome complement. This condition is also known as Triple X syndrome, where females have an extra X chromosome, resulting in a total of three X chromosomes. Therefore, this option is correct.

3. **Conclusion**:
- The correct answer is **Option D: Super Female**.
