The correct option is A ∮→B⋅→dl=μ0(iC+ε0dϕEdt)
According to the modified Ampere's circuital law,
→B→ the magnetic induction at any point on the path.
→dl→ is the length element of the path,
ic→ is the total conduction current through a surface enclosed by the closed path.
Id=ε0dϕdt→ the fictitious displacement current arising from the changing electric flux ϕe.
Hence, option (A) is correct.
