Which one of the following options represents the magnetic field $$\vec{B}$$ at O due to the current flowing in the given wire segments lying on the $$xy$$ plane?

A

$$\vec{B} = \dfrac{-\mu_0 I}{L}\left(\dfrac{3}{2} + \dfrac{1}{4\sqrt{2}\pi}\right)\hat{k}$$

B

$$\vec{B} = -\dfrac{\mu_0 I}{L}\left(\dfrac{3}{2} + \dfrac{1}{2\sqrt{2}\pi}\right)\hat{k}$$

C

$$\vec{B} = \dfrac{-\mu_0 I}{L}\left(1 + \dfrac{1}{4\sqrt{2}\pi}\right)\hat{k}$$

D

$$\vec{B} = \dfrac{-\mu_0 I}{L}\left(1 + \dfrac{1}{4\pi}\right)\hat{k}$$
