(C) \(A-III, B-I, C-IV, D-II\)
Step-by-step Solution
Detailed explanation
(A) \(B _{ ab }=\frac{\mu_0}{4 \pi} \frac{ I }{ r } \text { (out of the plane) }\) \(B _{ bcd }=\frac{\mu_0}{4 \pi} \frac{ I }{ r }(2 \pi) \text { (in the plane) }\) \(B _{ de }=\frac{\mu_0}{4 \pi} \frac{ I }{ r } \text { (out of the plane) }\) Hence magnetic field at \(O\) is…
