The Correct Option is B

Solution and Explanation

First, let's substitute the symbols with their corresponding operations:

Original expression: 18 A 12 C 6 D 2 B 5

After substitution: \(18 + 12 \div 6 \times 2 - 5\)

Now, we'll solve it step by step following the order of operations (PEMDAS/BODMAS):

  1. Division: \(12 \div 6 = 2\)
  2. Multiplication: \(2 \times 2 = 4\)
  3. Addition: \(18 + 4 = 22\)
  4. Subtraction: \(22 - 5 = 17\)

Final calculation:

\[ 18 + 12 \div 6 \times 2 - 5 = 18 + (12 \div 6) \times 2 - 5 = 18 + 2 \times 2 - 5 = 18 + 4 - 5 = 17 \]
