AGauss’s Law in Electrostatics  I∮E→·dl→=-dϕBdt
BFaraday's LawII∮B→·dA→=0 
CGauss’s Law in MagnetismIII∮B→·dl→=μ0ic+μ0∈0dϕEdt
DAmpere-Maxwell LawIV∮E→·ds→=q∈0

Choose the correct answer from the options given below :

Options:

Answer:
A
Solution:

(A) Gauss law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. So, ϕ=∮E→·ds→=q∈0

(B) Faraday’s law explains that the direction of the current will be opposite to the direction of flux that produced it, so ∮E→·dl→=-dϕBdt

(C) Gauss's law for magnetism states that the magnetic flux B across any closed surface is zero, so ∮B→·dA→=0

(D) Ampere’s Maxwell law is stated as 

∮B→·dl→=μ0ic+μ0∈0dϕEdt

Where ic=Conduction current and 

∈0dϕEdt=Displacement current

Thus, A-IV, B-I, C-II, D-III
