Which option gives a non-zero constant polynomial?

Answer and explanation

Correct answer: −5/2

A constant polynomial has no variable term, so its value does not depend on x. A non-zero constant polynomial must also have a value other than zero. Option C, −5/2, contains no x and is not equal to zero, so it is a non-zero constant polynomial. Option A is the zero polynomial, not a non-zero constant, even though it is constant in a broad sense. Option B contains x and is therefore a linear polynomial. Option D contains x² and is a quadratic polynomial. The classification depends on both conditions: absence of the variable and a non-zero constant value. Hence option C is the only answer satisfying the complete requirement.
