k1=turns ratio
k2=co-efficient of coupling
k1/k2=v1/v2
1/0.85=2/v2
v2=1.7v
k2=co-efficient of coupling
k1/k2=v1/v2
1/0.85=2/v2
v2=1.7v

Sorry. I made a blunder.
Actually, Current in transformer ckt is inversely proportional to voltage.
Why the correct option is (B).

Voltage induced =coefficent of coupling*voltage caliculated
if itwas not given we will simply take it as 1
v2/v1=n2/n1=1
v2=v1=2
Voltage induced = 2*.85 = 1.7v
if itwas not given we will simply take it as 1
v2/v1=n2/n1=1
v2=v1=2
Voltage induced = 2*.85 = 1.7v

@sheila & @poo.
The COEFFICIENT OF COUPLING of a transformer is dependent on the portion of the total flux lines that cuts both primary and secondary windings.
