The Correct Option is B
Solution and Explanation
A vector field \( \vec{F} \) is said to be solenoidal if its divergence is zero:
\[
\text{div}~\vec{F} = \nabla \cdot \vec{F} = 0
\]
This indicates there is no net flux out of any closed surface — a key property of incompressible fluid flow or magnetic fields.
