Hello :
cos60 = cos(-60)=0.5
        
             
        
        
        
Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:
18(0.25)=k=4.5
So you could say: IR=4.5 or I=4.5/R
        
             
        
        
        
Its may be A or C
i am not sure just try to help
