A) 1.96.
B) 1.65.
C) -1.65 and 1.65.
D) -1.96 and 1.96.

The critical value for a two-tailed hypothesis test with a p level of 0.05 is +/- 1.96 using the z statistic. This means that if the test statistic falls outside of the range of -1.96 to 1.96, we can reject the null hypothesis. Therefore, the correct answer is D, which lists both -1.96 and 1.96 as critical values.
