The two vectors $\vec A$ and $\vec B$ that are parallel to each other are

A

$\vec A = 3\hat i + 6\hat j + 9\hat k$ $\vec B = \hat i + 2\hat j + 3\hat k$

B

$\vec A = 3\hat i - 6\hat j + 9\hat k$ $\vec B = \hat i + 2\hat j + 3\hat k$

C

$\vec A = 2\hat i + 6\hat j - 9\hat k$ $\vec B = \hat i + 2\hat j - 3\hat k$

D

$\vec A = 2\hat i + 3\hat j + 3\hat k$ $\vec B = \hat i - 2\hat j - 3\hat k$
