Voltage ratio: v1/V2=N1/N2 = a
Current ratio: I1/I2=N2/N1 = 1/a
Ohmic ratio: Z1/Z2=R1/R2 = X1/X2 = (N1/N2)squared = (a) squared
Therefore, the correct answer is D.

Only option is "A" is correct. Although if question is: what you can determine than all the above, because.
Turns ratio= I2/I1 and reciprocal of it will make the "B" correct.
About, reflected impedance it is basically based on transformation ratio which is again reciprocal of turns ratio.

Reflected impedance is (R2/R1)^1/2 which is directly proportional to transformation ratio.

I think D is not correct option because the option B statement is wrong. Ratio of secondary and primary currents if it is so the option D is correct.

Transformer has one formula = Vp/Vs = Is/Ip = Np/Ns.
