Can anyone help me with this question? I am getting the voltage as 20/2 = 10 therefore then np/ns should equal 10 too. But there are no options where np/ns equals 10. Am I doing it wrong?

Thanks

Option (D) is the answer. The transformers aren't labelled with which side is input and output, so we can use the right side of (D) as the input side.
