An ideal fluid flows through a pipe that both narrows in cross-sectional area and increases in height. Which of the following statements must be true regarding the pressure change as the fluid moves into the narrower, higher section?

- **A.** The pressure must decrease.
- **B.** The pressure remains constant because the fluid is incompressible.
- **C.** The change in pressure cannot be determined without knowing the specific change in height and area.
- **D.** The pressure must increase to push the fluid upward.
