# A U-tube is filled with water and is being accelerated horizontally to the right with a constant acceleration \( a \). Which of the following describes the behavior of the water levels in the two vertical arms of the U-tube?

A U-tube is filled with water and is being accelerated horizontally to the right with a constant acceleration \( a \). Which of the following describes the behavior of the water levels in the two vertical arms of the U-tube?

- **A.** The water level in the right arm is higher than the water level in the left arm.
- **B.** The water levels in both arms remain equal.
- **C.** The water levels will oscillate and never reach a steady-state height difference.
- **D.** The water level in the left arm is higher than the water level in the right arm.
