Step-by-Step Solution
D < 0 means no real roots. Rita's D = -4 < 0, so only Rita's quadratic has no real roots. Sita (D=0) has equal roots and Gita (D=25) has distinct roots.
Answer: A) Rita
Three students each compute a discriminant: Sita gets D = 0, Gita gets D = 25, Rita gets D = -4.
Who among them has a quadratic with NO real roots?
