(C) Given expression: $[(3 \sqrt{8} + \sqrt{8}) 	imes (8 \sqrt{8} + 7 \sqrt{8})] - 98$Step $1$: Simplify the terms inside the parentheses.$(3 \sqrt{8} + \sqrt{8}) = 4 \sqrt{8}$$(8 \sqrt{8} + 7 \sqrt{8}) = 15 \sqrt{8}$Step $2$: Multiply the simplified terms.$(4 \sqrt{8}) 	imes (15 \sqrt{8}) = 4 	imes 15 	imes \sqrt{8} 	imes \sqrt{8}$$= 60 	imes 8 = 480$Step $3$: Subtract $98$ from the result.$480 - 98 = 382$Therefore,the correct option is $C$.

$[(3 \sqrt{8} + \sqrt{8}) \times (8 \sqrt{8} + 7 \sqrt{8})] - 98 = ?$
