Answer»

A sphere of radius 1m has an equation of the form $x^{2} + y^{2} + z^{2} = r^{2}$

Statement 1: For its surface, only 6 distinct numbers of normal vectors are possible.

Statement 2: At every point of its surface intersecting with the coordinate Axis, there will a normal vector along the direction of coordinate axis at those points.
