I KNOW YOU SEE THIS, please I need help I honestly just want the answer

Given the expression:
[tex]\sqrt[]{8a^3b^{11}}[/tex]The square root will be calculated as follows:
[tex]\begin{gathered} 8=4\times2=2^2\times2 \\ a^3=a^2\times a \\ b^{11}=b^{10}\times b=(b^5)^2\times b \\ \\ \sqrt[]{8a^3b^{11}}=2ab^5\sqrt[]{2ab} \end{gathered}[/tex]So, the answer will be option
