Let \( p \) be the line with the equation \( x-2y-1=0 \). Find the general form equations of all lines parallel to \( p \) such that their distance from \( p \) equals to \( \sqrt5 \).
\( x-2y+4=0;\ x-2y-6=0 \)
\( x-2y+\sqrt5=0;\ x-2y-\sqrt5=0 \)
\( x-2y-1+\sqrt5=0;\ x-2y-1-\sqrt5=0 \)
\( x-2y+6=0;\ x-2y-4=0 \)
