Correct option is (b).
The decision rule is: If p-value is less than k, reject H0 but if p-value is higher than or equal to k, do not reject H0.
The null-hypothesis (H0) states that a variable is not statistically significant. Therefore, when k = 0.05, it is higher than p-value of 0.032 (i.e. p-value < k), H0 is rejected, so the coefficient is not significant. When k = 0.01, it is lower than p-value of 0.032 (i.e. p-value > k), H0 is not rejected, so the coefficient is significant.
