The correct Answer is:
To solve the question regarding the duration of intrauterine life matched with the events completed, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Evaluate Statement i**: - **Statement**: End of the first month. Embryo heart is formed. - **Analysis**: By the end of the first month (around 4 weeks), the embryo is about 1/10 inch long, and the heart begins to beat around 18 days after conception. Therefore, this statement is **correct**. 2. **Evaluate Statement ii**: - **Statement**: End of the second month: Foetus develops limbs and digits. - **Analysis**: By the end of the second month (around 8 weeks), the fetus is approximately the size of a kidney bean, and the arms and legs are long enough to meet in front of the body, with distinct, slightly webbed fingers. Thus, this statement is **correct**. 3. **Evaluate Statement iii**: - **Statement**: End of the fifth month: Hair on head. - **Analysis**: By the end of the fifth month (around 20 weeks), the fetus becomes more active, and hair begins to grow on the head. Therefore, this statement is also **correct**. 4. **Evaluate Statement iv**: - **Statement**: End of the sixth month: Eyelashes are formed. - **Analysis**: By the end of the sixth month (around 24 weeks), the baby has developed visible eyebrows and eyelids, and the lungs are filled with amniotic fluid. Eyelashes are also formed during this time. Hence, this statement is **correct**. ### Conclusion: Since all four statements are correct, the answer to the question is option **4: 1, 2, 3, and 4**. ---
