The vector equation of the straight line...

The vector equation of the straight line `(1-x)/(3)=(y+1)/(-2)=(3-z)/(-1)` is

A

`vec(r) = (hat(i) - hat(j) +3hat(k)) + lamda (3hat(i) +2 hat(j) - hat(k))`

B

`vec(r) = (hat(i) - hat(j) +3hat(k)) + lamda (3hat(i)- 2hat(j)- hat(k))`

C

`vec(r)= (3hat(i) - 2hat(j)- hat(k)) + lamda (hat(i)- hat(j) +3hat(k))`

D

`vec(r) = (3hat(i) +2hat(j)- hat(k))+ lamda (hat(i)- hat(j) +3hat(k))`
