Assertion: The equation of the plane through the intesection of the planes `x+y+z=6 and 2x+3y+4z+5=0

Assertion: The equation of the plane through the intesection of the planes `x+y+z=6 and 2x+3y+4z+5=0` and the point `(4,4,40 is 29x+23y+17z=276.` Reason: Equation of the plane through the line of intersection of the planes `P_1=0 and P_2=0 is P_1 +lamda P_2=0, lamda!=0`. (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.
