Two vectors are given `vec(a) = -2hat(i) + hat(j) - 3hat(k)` and `vec(b) = 5hat(i) + 3hat(j) - 2hat(k)`. If `3hat(a) + 2vec(b) - vec(c) = 0` then third vector `vec(c)` is

A

`4hat(i) + 9 hat(j) - 13 hat(k)`

B

`-4hat(i) - 9hat(j) + 13 hat(k)`

C

`4hat(i) - 9hat(j) - 13hat(k)`

D

`2hat(i) - 3hat(j) - 13hat(k)`
