vectors

Question: The position vectors of radius are $2\hat i + \hat j + \hat k$ and $2\hat i - 3\hat j + \hat k$ while those of linear momentum are $2\hat i + 3\hat j - \hat k.$ Then the angular momentum is



1) $2\hat i - 4\hat k$
2) $4\hat i - 8\hat k$
3) $2\hat i - 4\hat j + 2\hat k$
4) $4\hat i - 8\hat k$
