Find the equation of the plane passing through the three points (2,2,0), (1,2,1), (-1,2,-2).

• A. (( vec{r}-(2 hat{i}+2 hat{j})).[(- hat{i}+ hat{k}) (-3 hat{i}-2 hat{k})] )=0
• B. (( vec{r}-(3 hat{i}-2 hat{k})).[(- hat{i}+ hat{k}) (2 hat{i}-2 hat{j})] )=0
• C. (( vec{r}+(2 hat{i}+2 hat{j})).[(- hat{i}- hat{k}) (-3 hat{i}-2 hat{k})] )=0
• D. (( vec{r}-(2 hat{i}+2 hat{j})).[(- hat{i}- hat{k}) (3 hat{i}+2 hat{k})] )=0
