The direction ratios of the diagonals of a cube which joins the origin to the opposite corner are (when the three concurrent edges of the cube are coordinate axes)

View answer and explanation

Correct option: B

1,1,1

Option B (

1,1,1

) is correct because the direction ratios of the diagonal of a cube joining the origin to the opposite corner are equal to the coordinates of that corner.
