In given figure, $X$ and $Y$ are two long straight parallel conductors each carrying a current of $2\,\, A.$ The force on each conductor is $F$ newtons. When the current in each is changed to $1\, A $ and reversed in direction, the force on each is now
  • A$F/4$ and unchanged in direction
  • B$F/2$ and reversed in direction
  • C$F/2$ and unchanged in direction
  • D$F/4$ and reversed in direction
