Which of the Following Best Describes How an χ² Goodness-Of-Fit

Which of the following best describes how an χ² goodness-of-fit test is used and performed?

A) The observed and expected frequencies are compared and a close match results in a large P-value, which supports rejection of the null hypothesis.
B) The observed and expected frequencies are compared and a close match results in a small P-value, which supports rejection of the null hypothesis.
C) The observed and expected frequencies are compared and a mismatch results in a large P-value, which supports rejection of the null hypothesis.
D) The observed and expected frequencies are compared and a mismatch results in a small P-value, which supports rejection of the null hypothesis.
