Given $\vec a=\hat i+2\hat j-3\hat k$, $\vec b=2\hat i-\hat j+\hat k$, and line $L$ has equation $\vec r\times\vec b=\vec a\times\vec b$.

If 'C' be the curve in the-y plane satisfying (where be the position vector of a variable point on the curve), then the minimum distance of line ' L ' from the centre of curve 'C' is-

Options:

Answer:
B
Solution:
