To find the chi-square statistic for a contingency table, we first need to calculate the expected values under the assumption of independence. We can then use the formula for chi-square: 
chi-square = sum((observed - expected)^2 / expected)

Using this formula and the expected values we calculated, we get a chi-square statistic of 2.741. Therefore, the best choice is (A).
