The correct answer is under.
The sentence describes how blood is propelled from the heart into the arteries. The phrase "under high pressure" accurately depicts this forceful ejection.

"In high pressure" lacks precision and is grammatically awkward. "Of high pressure" suggests a compositional aspect, rather than a dynamic force. Only "under high pressure" correctly conveys the physical process of blood being pushed into the arteries with considerable force.
