Correct option is BGiven:(65÷5)×[168+142×(6−4)](65÷5)× [\frac {16}8+ \frac{14}2×(6-4)](65÷5)×[816+214×(6−4)]Concept Used:Solution: (65÷5)×[168+142×(6−4)] =13×[2+7×2] =13×[2+14] =13×16=208(65÷5)× [\frac {16}8+ \frac{14}2×(6-4)] \\\ \\=13 × [2+7×2]\\\ \\=13 × [2+14]\\\ \\= 13 \times 16\\= 208(65÷5)×[816+214×(6−4)] =13×[2+7×2] =13×[2+14] =13×16=208
