    ans is 1 .....and one more think ..jb solenoid coil me pass aara hora hai tb flux increase hojate hai toh unko oppose krne ke liy induced current different direction me hoga means flux bdre hai toh spike negative me milna chiy pr according to option hme de rkha hai ki induced current ka mode le rkha hai toh yh allwys positive... se attached file dear... if Any query plz ask..

    I think option 1 m I right or wrong I don't 9....becoz induced current will flow in such a direction that the flux it produces tends to cancel the charge... so jab solenoid coli se due hai flux me change nahi hora toh koi induced current Nani hoga.. pr jab pass aayega toh flux me change hoga aur induced current flow hoga qki induced current uska oppose krega aur induced current ka spike mileg aaur jab solenoid coil me andr hoga toh flux constant toh koi induced current flow nahi hoga aur Spike bhi nHi milenege. aur jb vaps Bbahr aayega too again flux me change toh induced current flow hoga spike mikega.. toh ultimately we can say that the induced current will flow in such a direction that the flux it produces tends to cancel the charge according to the lenz law.. m I right or wrong vaishali ma'am nd abhishek sir??

    option 4 is correct. Because poore process me, solenoid me current pehle bdha, top pe jake constant hua, fir ghata, but bdhne ka rate jada tha as compare to ghatne ka rate, iske pehle current jada aaega, fir km. So option 4 is correct.
