Answer: (3) bce

Explanation:-
0   1    2    3    4   5   6   7   8    9       
a    b    c    d    e    f    g    h    i     j

dc x f – (bf – d) x d
Put the value of b = 1,  c = 2,  d = 3  & f = 5.

Then, the value of dc x f – (bf – d) x d  =  32 x 5 – (15 – 3) x 3
 = 160 – (12) x 3
 = 160 – 36
 = 124
Then, 124 is coded as  bce. 

Hence, the correct answer is option (3) bce.
