Answer:
option (B)
Explanation:
Intensity of unpolarised light, I = 25 W/m^2 
When it passes from first polarisr, the intensity of light becomes 

Let the intensity of light as it passes from second polariser is I''.
According to the law of Malus 

Where, θ be the angle between the axis first polariser and the second polariser.

I'' = 11.66 W/m^2
I'' = 11.7 W/m^2
 
        
             
        
        
        
Op here is another problem exactly like that. Just plug in your variables instead. And remember, time is never negative.
