Answer 1

The correct option is C 8

First cut: 2 north and 2 South Poles.

Second cut: Each of the two pieces were cut into two more pieces.

So, 4 North Poles and 4 South Poles.

Third cut: Each of the 4 pieces is cut into two more pieces.

So, 8 north and 8 South Poles.

Hence there will be 8 north poles in total.
