Let Q be the mirror image of the point $\displaystyle \mathrm{P}(1,2,1)$ with respect to the plane $\displaystyle x+2 y+2 z=16$. Let T be a plane passing through the point Q and contains the line $\displaystyle \vec{r}=-\hat{k}+\lambda(\hat{i}+\hat{j}+2 \hat{k}), \lambda \in \mathbb{R}$. Then, which of the following points lies on T ?
