 A 130 B 120 C 126 D 200 E 250
Explanation:

Detailed explanation-1: -The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus. An abnormal fetal heart rate may mean that your baby is not getting enough oxygen or that there are other problems.

Detailed explanation-2: -A normal fetal heart rate is between 110 and 160 beats per minute (bpm). Fetal bradyarrhythmia is generally defined as a sustained heart rate less than 110 beats per minute.

Detailed explanation-3: -You may have heard that your baby’s heart rate can predict its sex as early as the first trimester. If it’s over 140 bpm, you’re having a baby girl. Below 140 bpm, you’re carrying a boy.

Detailed explanation-4: -If the fetal heart rate is under 140 beats per minute (BPM), it’s a boy.

Detailed explanation-5: -This theory states that if the fetal heart rate is above 140 beats per minute (BPM), then the baby is more likely to be a girl. If the heart rate is below 140 BPM then the chances are that the baby will be a boy.
