The Accompanying Table Shows the Regression Results When Estimating Y

The accompanying table shows the regression results when estimating y = β₀ + β₁x₁ + β₂x₂ + β₃x₃ + ε. When testing whether or not x₁ and x₂ have the same influence on y, the null hypothesis is ________.

A) H₀: β₁ = β_{2
B) H0}: β₁ ≠ β_{2
C) H0}: β₁ + β₂ = β_{3
D) H0}: β₁ + β₂ = 0
