Answer
A

Explanation

A P-value of approximately 0 means the observed results would be extremely unlikely if the null hypothesis, H₀, were true. Therefore, we reject H₀; the choice is “reject.” This provides convincing evidence against the null hypothesis, though the direction of the difference depends on the alternative hypothesis.
