The correct option is C Degree of r(x) < Degree of (x–α)
If f(x) is divided by (x–α), then the quotient is q(x) and the remainder is r(x) such that r(x)≠0.
∴f(x)=(x–α)×q(x)+r(x)
Also, Degree of remainder < Degree of divisor
Thus, degree of r(x) < degree of (x–α).
Hence, the correct answer is option (3)
