To find the area under a normal curve to the left of a z-score of 1.23, you can use a standard normal distribution table or a calculator that provides cumulative probabilities for the standard normal distribution.

A z-score of 1.23 corresponds to an area of approximately 0.8907 (or 89.07%) to the left of that z-score.

Therefore, the correct answer is:

**89.07 percent**
