According to Nagele's rule, what is the due date for a woman whose last menstrual period began on October 26?

Nagele's rule is a standard formula used to estimate a woman's due date based on her last menstrual period (LMP). The rule states that you can calculate the estimated due date by taking the first day of the last menstrual period, adding one year, subtracting three months, and then adding seven days.

In this case, if the last menstrual period began on October 26, we first add one year, which brings us to October 26 of the following year. Then we subtract three months, which gives us July 26. Finally, we add seven days to this date, which results in a due date of August 2.

Therefore, the calculation leads us to a due date of August 2, making this the correct answer.
