Answer:
B. (x,y,z).
Step-by-step explanation:
We represent the coordinate of a point in one dimension as x on the line. We represent the coordinate of a point in two dimension (plane) as (x,y). Similarly we represent the coordinate of a point which lie in the space (three dimension) as (x,y,z) .Here x is the x-coordinate of the point,
y is the y-coordinate of the point,
and z is the z-coordinate of the point. Hence (x,y,z) represent a point a point in a three dimensional Cartesian System.
