In the following list identify a pair of planes such that the distance of planes from the plane $\alpha$ is the same as the distance between the point $A=[0;0;1]$ and the plane \(\alpha \).
\[
\alpha \colon 2x + y - z - 5 = 0
\]
\(\begin{aligned}[t] 2x + y - z +\phantom{ 1}1& = 0&
\\2x + y - z - 11& = 0
\\ \end{aligned}\)
\(\begin{aligned}[t] 2x + y - z +\phantom{ 1}1& = 0&
\\2x + y - z - 10& = 0
\\ \end{aligned}\)
\(\begin{aligned}[t] 2x + y - z +\phantom{ 1}1& = 0&
\\2x + y - z - 12& = 0
\\ \end{aligned}\)
\(\begin{aligned}[t] 2x + y - z + 1& = 0&
\\2x + y - z - 9& = 0
\\ \end{aligned}\)
