0.4:1 is for (Ns/Np)^2 = Zs/Zp.
2.5:1 is for (Np/Ns)^2 = Zp/Zs.
I think that both of them are correct, the only mistake is putting both of them in the choices that is why it got a little confusing.

The followed formula is Ns/Np = underroot of Zs/Zp;
Thus Zs si Zload which is 160 ohms and Zp is 1kohms.
Answer is 0.4:1.
Thus Zs si Zload which is 160 ohms and Zp is 1kohms.
Answer is 0.4:1.

(N1/N2)^2 = R2/R1.
So the answer is option B.
So the answer is option B.

Answer should be a Turn and transform ratio is same N1/N2.
So answer A.
So answer A.

N2/N1 = turn ratio.
N1/N2 = Transformation ratio.
N2/N1=under root R2/R1.
SO 0.4:1.
N1/N2 = Transformation ratio.
N2/N1=under root R2/R1.
SO 0.4:1.

N2/N1= √(r2/r1) = k.

Is * 1000 = Ip * 160 and Ip/Is = k = N1/N2.
k = 1000/160 = 6.25:1.
k = 1000/160 = 6.25:1.

k = sqrt(r2/r1).
k = sqrt(160/1000),
k = 0.4.
Therefore ratio will be 0.4:1.
k = sqrt(160/1000),
k = 0.4.
Therefore ratio will be 0.4:1.

N2/N1 = V2/V1 = I1/I2 = K = SQR OF Rload/Rsource.
