1. Answer:

   C

   c and a have the same sign

   Given that the zeros of the quadratic polynomial ax2+bx+c,c=0 are equal.

   => Value of the discriminant(D) has to be zero.

   =>b2−4ac=0

   =>b2=4ac

   Since. L.H.S b2 cannot be negative, thus, R.H.S. can also be never negative.

   Therefore, a and c must be of the same sign.
