Answer» CORRECT option is (b) eleventh For explanation: Blood flow detectors based on ultrasonic Doppler shift can detect foetal pulse as early as the tenth WEEK of pregnancy and in nearly all cases by the twelfth week. At about 20 weeks it is possible to detect multiple pregnancies especially if two instruments are used together and the pulse RATES compared. Intrauterine DEATH of the foetus can also be diagnosed.
