MCQ
The coordinates of any point, which lies on $x$ axis are:
  • A
    $(0, x, 0)$
  • ✓
    $(x, 0, 0)$
  • C
    $(x, x, 0)$
  • D
    $(x, x, x)$
✓

Answer

Correct option: B.
$(x, 0, 0)$
In $3-$dimensional plane, the point which lies on $x-$axis does not have any part in $y$ and $z$ axes.
At that point, the value of $y$ and $z$ will be $0.$
Hence, coordinate of any point which lies on $x$ axis are $(x, 0, 0)$.
