Answer: B - Hypertension is not a known risk factor for ectopic pregnancy.

Heavy smoking is a risk factor for various complications, including ectopic pregnancy. In vitro fertilization and other treatments for infertility, as well as infertility issues themselves, are also risk factors for ectopic pregnancy. Other risk factors include advanced maternal age, inflammation of the fallopian tubes, pelvic inflammatory disease, pregnancy after tubal ligation or while using an IUD, prior damage to the fallopian tubes, and previous ectopic pregnancy.
