Final answer:
The recurrent pelvic infections in a woman's health history puts her at greater risk for an ectopic pregnancy. It's primarily because pelvic infections can lead to scar tissue in the fallopian tubes, causing an obstruction for the embryo and leading to ectopic pregnancy.
Step-by-step explanation:
Ectopic pregnancy, which is the implantation of the embryo outside the uterus mainly in the fallopian tubes, can be significantly influenced by various factors within a woman's health history. For your question, the data that might increase a woman's risk of ectopic pregnancy would primarily be 'b. Recurrent pelvic infections'.
This is because pelvic infections, notably sexually transmitted bacterial infections like gonorrhea and chlamydia, can lead to pelvic inflammatory disease (PID). PID can result in scar tissue formations within the fallopian tubes. This scar tissue can create obstacles for the embryo traversing the fallopian tubes to the uterus, causing it to implant within the tube itself and thus leading to ectopic pregnancy. Options such as ovarian cysts, use of oral contraceptives, or heavy menstrual flow, though related to reproductive health, have not been directly linked to increased risks for ectopic pregnancy.
