  • According to me , option 4th is correct.

Explanation:

During the first trimester, the foetus is very sensitive to anything that interferes with the steps involved.

TORCH infecting ( toxoplasmosis and other rubella, cytomegaloviruses and herpes simplex ) are major causes of miscarrage or abortion in first trimester. So, confirming IUP option is correct.

Thalidomide was used to treat the symptoms of morning sickness during pregnancy, it lead to heart disorders and non- formation of long bones . So,documenting fetal heart activity option is also correct.

Thus, both A and C options are correct.
