B. 2A + XXX
C. 2A + XO
D. 2A + XY

Answer

**Step-by-Step Solution:**

1. **Understanding Turner Syndrome:**
- Turner syndrome is a genetic disorder that primarily affects females. It is characterized by the absence of one of the X chromosomes.

2. **Chromosomal Composition in Turner Syndrome:**
- Normally, females have two X chromosomes (XX). However, in Turner syndrome, there is only one X chromosome present, leading to a chromosomal composition of XO (where "O" indicates the absence of a second X chromosome).

3. **Identifying the Chromosomal Cause:**
- The condition is caused by the absence of one of the X chromosomes. Therefore, the chromosomal makeup is not XX but XO.

4. **Conclusion:**
- The correct answer to the question "Turner's syndrome of female is due to the chromosome" is that it is due to the presence of only one X chromosome (XO).

**Final Answer:**
Turner's syndrome in females is due to the absence of one X chromosome, resulting in the chromosomal composition XO.
