For a one-tailed test with α = .005 and a lower tail, we need to find the z value that corresponds to the area of .005 in the tail of the standard normal distribution. Looking at the z-table, we can see that the closest value to .005 is .0049, which corresponds to a z-score of -2.575. Therefore, the correct choice is A.
