Final answer:

To find the components of the vector {r} = 2{r_1} - {r_2} + 3{r_3}, we need specific values for {r_1}, {r_2}, and {r_3}.

Step-by-step explanation:

In order to find the components of the vector {r} = 2{r_1} - {r_2} + 3{r_3}, we can break it down into its x, y, and z components.

The x component is 2{r_1}, the y component is -{r_2}, and the z component is 3{r_3}.

Since we don't have specific values for {r_1}, {r_2}, and {r_3}, we cannot calculate the exact components of {r}. Therefore, none of the given options (A, B, C, D) are correct.
