A quadratic relation is nothing but a quadratic equation of the form ax^{2}+b x +c = 0 where a cannot be equal to zero. The power of the variable x should always be equal to 2.

A quadratic equation is an equation of second degree. The highest degree term is of second degree.

So, options A and C are the only correct options.
