Figure shows arrangement of three long parallel conducting wires, each carrying equal current coming out of page. Four points \( A, B, C \) and \( D \) are also marked in the figure, showing distances between points and wires. All points lie in the same plane which \( \overrightarrow{d l} \) is perpendicular to the wires.
\begin{tabular}{|l|l|l|l|}
\hline i. & At point A, & p. & magnitude of the magnetic field is maximum \\
\hline ii. & At point B, & q. & magnitude of the magnetic field is neither maximum nor minimum in magnitude \\
\hline iii. & At point C, & r. & magnitude of the magnetic field is minimum \\
\hline iv. & At point D, & s. & direction of the magnetic field is along negative \( y \) axis. \\
