Answer
Choice C
Work Step by Step
The given expression, $
\sqrt[]{8}
,$ is closest to $3$ since $3^2=9.$
The given expression, $
\sqrt[]{20}
,$ is closest to $4$ since $4^2=16.$
Hence, the length of the bent wire, $
\sqrt{8}+\sqrt{20}
,$ is closest to
\begin{array}{l}\require{cancel}
3+4
\\\\=
7
.\end{array}
Hence, $\text{
Choice C
