A line joining the points $(1,2,0)$ and $(4,13,5)$ is perpendicular to a plane. Then the coefficients of $x,y$ and $z$ in the equation of the plane are respectively:

If a line is perpendicular to a plane, the DRs of the line are the coefficients of $x,y,z$ in the plane equation (as they represent the normal vector).DRs of the line joining $(1,2,0)$ and $(4,13,5)$:
$$(4-1),(13-2),(5-0)=(3,11,5)$$
Thus, the coefficients are $3,11,5$.
