Correct option is
(A) $6,-\frac{17}{3}$
Equation of plane $\bar{r} \cdot(3 \hat{i}+2 \hat{j}+6 \hat{k})=13$
i.e. $3 x+2 y+6 z-13=0$
Given point $(2,3, \lambda)$
distance of plane from the points $=\left|\frac{a x_{1}+b y_{1}+c z_{1}+d}{\sqrt{a^{2}+b^{2}+c^{2}}}\right|$
$
\begin{array}{l}
5=\left|\frac{3(2)+2(3)+6 \lambda-13}{\sqrt{9+4+36}}\right| \\
\therefore 5=\left|\frac{6 \lambda-1}{7}\right|
\end{array}
$
$\Rightarrow 6 \lambda-1=\pm 35$
$\Rightarrow 6 \lambda=36,6 \lambda=-34$
$
\therefore \lambda=6, \lambda=-\frac{17}{3}
$
