Answer : 3. "9"
Explanation :

Answer: C) 9 Explanation: The given expression can be simplified as 6 ÷ 2 (1 + 2) The expression can be simplified further by the order of operations, using BODMAS rule.   First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.   Now, the expression becomes 6 ÷ 2 (3)   According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3. 6 ÷ 2 × 3 = 3 × 3 = 9 But not  6÷2×3 = 6 ÷ 6 = 1     Hence, 6 ÷ 2 (1 + 2) = 9.
