C)H₀: population parameter < constant vs.H₁: population parameter ≥ constant
D)H₀: population parameter = constant vs.H₁: population parameter ≠ constant

The null hypothesis (H₀) in a one-sample hypothesis test always assumes that the population parameter is equal to a constant value, so option D is the only valid choice. Option A includes a not equal sign in the null hypothesis, which is incorrect. Options B and C have an inequality in the null hypothesis, which is also incorrect.
