If ‘A’ stands for ‘÷’ , ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘–‘, what will come in place of the question mark in the following equation?
8 B 9 C 49 A 7 D 25 = ?

Given:

8 B 9 C 49 A 7 D 25 = ?
After using the sign equation will be:
8 × 9 + 49 ÷ 7 – 25 = ?
? = 8 × 9 + 7 – 25
? = 72 + 7 – 25
? = 79 - 25
? = 54

Thus, the correct option is: (c)
