Explanation
Choice A Reason: This is incorrect because maternal diabetes is a condition where the mother has high blood sugar levels during pregnancy. It can cause polyhydramnios, or excess amniotic fluid, not oligohydramnios, or low amniotic fluid.
Choice B Reason: This is correct because fetal anencephaly is a congenital defect where the fetus lacks parts of the brain and skull. It can cause oligohydramnios, as the fetus does not produce enough urine to contribute to the amniotic fluid volume.
Choice C Reason: This is incorrect because placental abruption is a complication where the placenta detaches from the uterine wall before delivery. It can cause bleeding, pain, and fetal distress, but not oligohydramnios.
Choice D Reason: This is incorrect because neural tube defects are congenital defects where the spinal cord or brain does not develop properly. They can cause various neurological problems, but not oligohydramnios.

Choice B Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 18.
Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.
Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.
