There are two wires \( a b \) and \( c d \) in a vertical plane as shown in figure. Direction of current in wire \( a b \) is rightwards. Choose the correct options.
(a) If wire \( a b \) is fixed, then wire \( c d \) can be kept in equilibrium by the current in \( c d \) in leftward direction
(b) Equilibrium of wire \( c d \) will be stable equilibrium
(c) If wire \( c d \) is fixed, then wire \( a b \) can be kept in equilibrium by flowing current in \( c d \) in rightward direction
(d) Equilibrium of wire \( a b \) will be stable equilibrium
