Final Answer:
Rapid fall < 100, any time during contractions corresponds to D) Late Decelerations.
Step-by-step explanation:
The correct option is D. Late Decelerations.
Rapid Fall < 100: This refers to a quick decrease in fetal heart rate below 100 beats per minute.
Any Time During Contractions: Late Decelerations are characterized by the delay in the return of the fetal heart rate to the baseline, and they occur after the peak of the contraction. The description "any time during contractions" aligns with the pattern of late decelerations.
Late Decelerations: These decelerations are associated with uteroplacental insufficiency, where there is an inadequate oxygen supply to the fetus. The late onset and recovery after the contraction make them distinct from other types of decelerations.
Understanding these characteristics, the correct option for the described scenario is D) Late Decelerations.
