An ideal fluid is defined as being incompressible and having no viscosity. What are the physical implications of these two properties during fluid flow?

- **A.** The pressure is the same at all points in the fluid and the density is constant.
- **B.** The fluid has no mass and can flow through any opening without resistance.
- **C.** The fluid’s density remains constant and there is no energy loss due to internal friction.
- **D.** The fluid’s velocity is constant everywhere and it cannot be compressed.
