Solution

The correct option is D a-q,s; b-p,r; c-p,r; d-q,s
if $i_{1} ↑$ then $i_{2}$ has to be anticlockwise has also opposite flow of current
$∴$ they will attract
b) if $i_{1} ↓$ then $i_{2}$ has to be clockwise
same direction flow
$∴$ they will repel
c) this is same as case (b)
d) same reasons as for case a
