Ultrasound is the technique used to observe fetal movement and activity levels throughout gestation. It provides real-time images of the developing fetus, allowing researchers to monitor fetal behavior, such as kicking and spinning, and establish patterns of activity.

A and C are not relevant to determining fetal activity levels, and D is not a common or appropriate imaging technique for prenatal purposes.
