The correct option is
D [→r−→a,→u,→v]=0Lets recall non-parametric vector equation.
Suppose we want to define a plane that passes through P0 and is perpendicular to n.
NOTE: There will be only one such plane because fixing a direction fixes the orientation of our plane.
Lets define r as set of all points which lie on the plane.
Now, observe that r−r0 lies on the plane itself because both
P,P0 lie on the plane.
Thus, equation of plane becomes
(r−r0).n=0 (because cos90=0)
In the given case , n=u×v and r0=a
Replacing in our equation we get, (r−a).(u×v)=0
[r−a,u,v]=0
