Concept:Use BODMAS rule and solve the innermost bracket first.Explanation:Start with the innermost bracket: (2−4)=−2.Then inside the curly braces: 2−(−2)=4.The expression becomes 2−[2−3×4÷2].Apply division and multiplication from left to right: 3×4÷2=12÷2=6.So 2−[2−6]=2−[−4].Final calculation: 2−(−4)=2+4=6.Answer:6 (Option C)
