Explanation / Answer
The statistical significance is measured by the p-value from the t test. For the intercept, we have here the t statistic value as 2.489 for which the p-value is given to be 0.021.
As the p-value here is 0.021 < 0.05 but 0.021 > 0.01, therefore the test is significant at the 5% level of significance but not at the 1% level of significance. Therefore 95% is the correct answer here.
