Hope it helps! Brainiest Answer would be amazing!
Either it don't have a magnetic field around them or it's not a sheet steel door
As we know that in transformers we have

here we know that




now from above equation we will have


now we have to reduce this voltage to final voltage of V = 4 V
so again we will have



so we need to take such a winding whose ratio is 1:5
So it is satisfied in X


so answer will be
<u>B)- X</u>
