Simplify: $7\sqrt{48}-\sqrt{72}-\sqrt{27}+3\sqrt{2}$

The correct option is A: $25\sqrt{3}-3\sqrt{2}$
$7\sqrt{48}-\sqrt{72}-\sqrt{27}+3\sqrt{2}$

$=7\sqrt{\underset{–}{4\times 4}\times 3}-\sqrt{\underset{–}{6\times 6}\times 2}-\sqrt{\underset{–}{3\times 3}\times 3}+3\sqrt{2}$

$=(7\times 4\sqrt{3})-6\sqrt{2}-3\sqrt{3}+3\sqrt{2}$

$=\left(28\sqrt{3}\right)-3\sqrt{3}+3\sqrt{2}-6\sqrt{2}$

$=(28-3)\sqrt{3}+(3-6)\sqrt{2}$

$=25\sqrt{3}-3\sqrt{2}$
