Explanation:

Let's break down the expression step by step:

- Start with the innermost parentheses: (501 + 247 - 386)

- Calculation: 501 + 247 = 748

- Then, 748 - 386 = 362

- Substitute back into the expression: [12 × 5 - {200 - 362}]

- Perform the operation in the curly braces: {200 - 362} = -162

- Continue with the expression: [12 × 5 - (-162)]

- Simplify: 12 × 5 = 60

- So, the expression becomes: [60 + 162]

- Add: 60 + 162 = 222

- Finally, divide by 2: 222 ÷ 2 = 111

- Correct Answer: Option 2 - 111
