(iii) At puberty , in female each ovary contain about 60,000 - 80,000 primary follicles.
Choose the correct Statement from the above

Options

A. i, ii and iii
B. i and ii
C. iii only
D. i only

Answer

To solve the question, we need to evaluate each of the three statements provided and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Statement (i)**:
- The statement claims that the first movements of the fetus are usually observed during the 7th month of pregnancy.
- **Analysis**: The first movements of the fetus, known as "quickening," typically occur around the 18th to 20th week of pregnancy, which is approximately the 5th month. Therefore, this statement is **incorrect**.

2. **Evaluate Statement (ii)**:
- The statement claims that the umbilical cord possesses 100 percent fetal blood.
- **Analysis**: The umbilical cord contains two umbilical arteries and one umbilical vein. The arteries carry deoxygenated blood from the fetus to the placenta, while the vein carries oxygenated blood from the placenta to the fetus. Thus, the umbilical cord does not contain 100 percent fetal blood, as it also involves maternal blood exchange. Therefore, this statement is **incorrect**.

3. **Evaluate Statement (iii)**:
- The statement claims that at puberty, each ovary in females contains about 60,000 to 80,000 primary follicles.
- **Analysis**: This statement is accurate. At puberty, females typically have around 60,000 to 80,000 primary follicles in each ovary, which can decrease over time. Therefore, this statement is **correct**.

### Conclusion:
- The only correct statement among the three is Statement (iii).

### Answer:
The correct statement is **(iii)**: At puberty, in females, each ovary contains about 60,000 - 80,000 primary follicles.
