Explanation: A streamline is defined as an imaginary line within the flow such that the tangent at any point on it indicates the velocity at that point. Flow can only be along the velocity, never perpendicular to it. Hence, the movement of fluid mass can only be along the streamlines and never across them.

The correct answer is option B.
Explanation:
Fluid flow can be categorized into two types: laminar flow and turbulent flow. In laminar flow, the movement of fluid mass occurs along the streamlines, while in turbulent flow, the movement can also occur across the streamlines.
1. Laminar flow:
In laminar flow, the fluid particles move smoothly and in an organized manner along well-defined streamlines. The fluid particles do not mix with each other and move parallel to the boundaries of the flow passage. This type of flow is characterized by low velocities and high viscosity.
2. Turbulent flow:
In turbulent flow, the fluid particles move chaotically and mix with each other. The flow is characterized by eddies and swirling motions, resulting in a random movement of fluid particles. The fluid particles may move across the streamlines, creating a complex pattern of flow. Turbulent flow occurs at higher velocities and lower viscosity.
Reason why option B is correct:
Option B states that the movement of fluid mass can be along the streamlines but never across them. This statement is correct because in laminar flow, the fluid particles move strictly along the streamlines and do not cross them. Laminar flow is a type of flow where the fluid particles move in an organized manner and do not mix with each other. Therefore, option B accurately describes the behavior of fluid mass in laminar flow.
Reason why other options are incorrect:
- Option A states that the movement of fluid mass can either be along the streamlines or across them. This is incorrect because in laminar flow, the fluid particles only move along the streamlines and not across them.
- Option C states that the movement of fluid mass can never be along the streamlines but can be across them. This is incorrect because in laminar flow, the fluid particles strictly move along the streamlines and do not cross them.
- Option D states that the movement of fluid mass can neither be along the streamlines nor across them. This is incorrect because in laminar flow, the fluid particles move strictly along the streamlines.
Therefore, the correct answer is option B, which accurately describes the movement of fluid mass in laminar flow.

Therefore, the correct answer is option B, which accurately describes the movement of fluid mass in laminar flow.
