Solution
Hint: use condition of point on a place.
Step 1: Locate the point
Given the point is (3,0,–4)
The coordinate of xz-plane is (x,0,k) l.e., the value of y-coordinate is zero.
So the given point (3,0,–4) lies on the xz-plane as the value of y-coordinate is zero.
Therefore, option D is correct
