To determine the first and last fertile unsafe days of Charlotte's monthly cycle, we need to use the following formula:

First fertile day = shortest cycle length - 18
Last fertile day = longest cycle length - 10

Using the values given in the problem, we get:

First fertile day = 30 - 18 = 12
Last fertile day = 34 - 10 = 24

Therefore, the first and last fertile days of Charlotte's monthly cycle are from Day 12 to Day 23. The closest option is C, 12-23.
