Let's solve ~
[tex]\qquad \looparrowright \sf - 7 \sqrt{80 {x}^{4} y {}^{2} } [/tex]
[tex]\qquad \looparrowright \sf - 7 \sqrt{2 {}^{4} \times 5 \times {x}^{4} \times {y}^{2} } [/tex]
[tex]\qquad \looparrowright \sf - 7 \times {2}^{2} \times {x}^{2} \times y \times \sqrt{5} [/tex]
[tex]\qquad \looparrowright \sf - 28 {x}^{2} y \sqrt{5} [/tex]
Therefore, Option D is correct ~
