Force on D A due to the long wire is towards left while on B C is towards right.

a	Counterclockwise	To the left	To the left
b	Counterclockwise	To the right	To the left
c	Clockwise	To the right	To the left
d	Clockwise	To the left	To the right

As the flux decreases, to maintain flux, current in the loop is clockwise. Force on DA due to the long wire is towards left while on BC is towards right.

As the flux decreases, to maintain flux, current in the loop is clockwise. Force on $D A$ due to the long wire is towards left while on $BC$ is towards right.
