The fetal heart rate (FHR) is first visualized at about how many weeks’ gestation, and what does FHR stand for?

Explanation:
Fetal heart activity becomes detectable by ultrasound around six weeks of gestation, often with a transvaginal scan. FHR stands for fetal heart rate, which indicates how fast the fetal heart is beating (measured in beats per minute). This pairing is the best because it correctly links the earliest visual detection timing with what FHR abbreviates. Remember, FHR refers to rate, not rhythm. Early on the heart rate is typically about 90–110 bpm at first detection and then rises as pregnancy progresses.
