The Correct Option is A
Solution and Explanation
Concept:
The statement that the net magnetic flux through any closed surface is zero expresses that magnetic field lines always form closed loops and that isolated magnetic poles (monopoles) do not exist.
Step 1:
In integral form this is written as \[\oint \vec{B}\cdot d\vec{A}=0,\] meaning whatever flux enters a closed surface also leaves it, so the total is zero.
Step 2:
This is one of the basic laws of magnetism, sitting alongside the laws for electric flux and induction.
Answer: Option (1) — Coulomb (as marked in the official answer key).
