Option (A) is correct.
Turns ratio=1
Co-efficient=0.85.
o/p vol tage = 2 * 0.85 = 1.7v.
Turns ratio=1
Co-efficient=0.85.
o/p vol tage = 2 * 0.85 = 1.7v.

K =V2/V1=N2/N1=1, V1=2
V2=K*V1= 1 * 2 = 2v.
The coefficient of coupling = .85 =85*1/100= 85%
That mean 85% primary Flux passes through secondary.
So, 85% secondary Volts, V2=0.85*2=(85/100)*2 = 1.7v
V2=K*V1= 1 * 2 = 2v.
The coefficient of coupling = .85 =85*1/100= 85%
That mean 85% primary Flux passes through secondary.
So, 85% secondary Volts, V2=0.85*2=(85/100)*2 = 1.7v
