Assertion: The direction ratios of the line joining orign and point `(x,y,z)` are x,y,z., Reason: If O be the origin and `P(x,y,z)` is a point in space and OP =r then direction cosines of OP are `x/r,y/r,z/r.` (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.
