"LET the equation `ax^2+bx+c=0` has no real roots
Assertion (A): `c(a+b+c)gt0`, Reason (R): A quadratic expression `ax^2+bx+c ` has signs same as that of al for all real x if the roots of the corresponding equation `ax^2+bx+c=0` are imaginary. (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."
