    Answer : Option B

    Explanation :

    4 | x            y = (5 x 1 + 4) = 9
     --------
     5 | y -1         x = (4 x y + 1) = (4 x 9 + 1) = 37
     --------
       | 1 -4
    
     Now, 37 when divided successively by 5 and 4, we get
    
     5 | 37
     ---------
     4 | 7 - 2
     ---------
       | 1 - 3
     
     Respective remainders are 2 and 3.
