Solution

The correct option is D 1
Here f(x) represent dividend and g(x) represent divisor

g(x)= quadratic polynomial =ax2+bx+c

deg(g(x))=2, deg(f(x))=4

quotient q(x) is of degree =2 (=42)
According to the division algorithm, deg(g(x)) > deg(r(x)) > 0
2 > deg(r(x)) > 0

Remainder R(x)= degree 1 or less than 1.
