A non-planar loop of conducting wire carrying a current \( \mathrm{I} \) is placed as shown in the figure. Each of the straight sections of the loop is of length \( 2 \mathrm{a} \). The magnetic field due to this loop at the point \( \mathrm{P} \) (a, 0 , a) points in the direction
(A) \( \frac{1}{\sqrt{2}}(-\hat{\mathrm{j}}+\hat{\mathrm{k}}) \)
(B) \( \frac{1}{\sqrt{3}}(-\hat{\mathrm{j}}+\hat{\mathrm{k}}+\hat{\mathrm{i}}) \)
(C) \( \frac{1}{\sqrt{3}}(\hat{i}+\hat{j}+\hat{k}) \)
(D) \( \frac{1}{\sqrt{2}}(\hat{i}+\hat{k}) \)
