As learnt in

Mutual Induction -

Whenever the current passing throug the coil or circuit changes, the magnetic flux linked with neighbouring coil or circuit will also change.

- wherein

 

  Two loops will repel each other when current in the two loops are in opposite sense. This will happen when current in loop Y will oppose the field produced by loop X, i.e. flux through loop Y is increasing or current in loop X is increasing.

decreasing

This option is incorrect

Option 3)
