The seepage analysis in earthen dams is carried out by drawing flownet which consists of equipotential and stream lines. For a homogeneous and isotropic earthen dam, these two lines are always
(A) orthogonal to each other
(B) parallel to each other
(C) divergent to each other
(D) convergent to each other
