$\overrightarrow A = 2\hat i + \hat j,\,B = 3\hat j - \hat k$ and $\overrightarrow C = 6\hat i - 2\hat k$.Value of $\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C $ would be
- A$20\hat i + 5\hat j + 4\hat k$
- B$20\hat i - 5\hat j - 4\hat k$
- C$4\hat i + 5\hat j + 20\hat k$
- D$5\hat i + 4\hat j + 10\hat k$
