Let `(a_1, a_2, a_3, a_4, a_5)` denote a re-arrangement of `(1, -4, 6, 7, -10).` Then the equation `a_1x^4 + a_2x^3 + a_3x^2 + a_4x + a_5 = 0` has at least two real roots. Statement (2): If `ax^2+bx+c=0 & a+b+c=0,` (i.e. in a polynomial the sum of coefficients is zero) then x = 1 is root of `ax^2 + bx + c = 0.`

A

at least two real roots

B

all four real roots

C

only imaginary roots

D
