Lines \( y=x+i \) \& \( y=-x+j \) are drawn in \( x-y \) plane such that \( i \in\{1,2,3,4\} \& j \in\{1,2,3,4,5,6\} \). If \( m \) represents the total number of squares formed by the lines and \( n \) represents the total number of
W triangles formed by the given lines \& \( x \)-axis, then correct option/s is/are-
(A) \( m+n=50 \)
(B) \( m-n=2 \)
(C) \( m+n=48 \)
(D) \( m-n=4 \)
