To solve the equation, we need to substitute the operations based on the given symbols:

- "D" denotes division. So, 51 D 17 is the same as 51 ÷ 17.

- "A" denotes addition. So, we add the result to the next operation.

- "B" denotes multiplication. So, 21 B 9 is the same as 21 × 9.

- "C" denotes subtraction. So, we subtract 78.

- "A" denotes addition again. Add the result of the final operation.

- 16 D 4 is the same as 16 ÷ 4.

Now let's compute step by step:

- 51 ÷ 17 = 3

- 21 × 9 = 189

- Add these results: 3 + 189 = 192

- Subtract 78: 192 - 78 = 114

- 16 ÷ 4 = 4

- Add this result: 114 + 4 = 118

- Option 3: 118 is the correct answer.
