Explanation:

Let's decode the symbols:

- A = Addition (+)

- B = Multiplication (×)

- C = Subtraction (-)

- D = Division (÷)

The expression:

66 A (132 D 12) C (4 A 3) B (15 D 5) A 16 B (-3)

Stepwise calculation:

- 132 D 12 ? 132 ÷ 12 = 11

- 4 A 3 ? 4 + 3 = 7

- 15 D 5 ? 15 ÷ 5 = 3

Now substitute:

66 + 11 - (7 × 3) + 16 × (-3)

Continue:

- 7 × 3 = 21

- 16 × (-3) = -48

So,

66 + 11 - 21 - 48

Which is:

77 - 21 - 48

= 56 - 48

= 8

- Option 1: 8 (This is the correct answer)

- Option 2: 10 (Incorrect)

- Option 3: 6 (Incorrect)

- Option 4: 56 (Incorrect)
