  • A
    The velocity of a fluid particle remains constant.
  • B
    The velocity of all fluid particles crossing a given position is constant.
  • C
    The velocity of all fluid particles at a given instant is constant.
  • D
    The speed of a fluid particle remains constant.

Answer

  1. The velocity of all fluid particles crossing a given position is constant.

Explanation:

As discussed above for a streamline flow of a liquid velocity of each particle at a particular cross-section is constant, because Av = constant (law of continuity) between two cross-section of a tube of flow. So we can say that along a streamline, the velocity of every fluid particle while crossing a given position is the same.
