Ordering Z-Scores from Cumulative Probabilities

Question

The `invNorm` function finds the z-score corresponding to a given cumulative probability for the standard normal distribution. The results of four `invNorm` commands are shown below.

A: `invNorm(0.05)` ≈ $$-1.645$$
B: `invNorm(0.10)` ≈ $$-1.282$$
C: `invNorm(0.50)` = $$0$$
D: `invNorm(0.90)` ≈ $$1.282$$

Which of the following correctly orders the commands from the lowest resulting z-score to the highest?
