If We Are Testing the Significance of the Independent Variable $\beta$

If we are testing the significance of the independent variable X₁ and we reject the null hypothesis H₀: $\beta$ ₁ = 0,we conclude that:

A) X₁ is significantly related to y.
B) X₁ is not significantly related to y.
C) X₁ is an unimportant independent variable.
D) $\beta$ ₁ is significantly related to the dependent variable y.
