Dear Student,

as the current in primary sustain the field is from N to L in secondary coil 
as the we switch of the primary the flux through the secondary will decrease intantatneously
to maintan the flux the current will induce such that in secondary that it will produce field from N to L
hence the current should flow from N to L by right hand curl rule 
option 2Regards
