Final answer:
In a threatened abortion, vaginal bleeding and cramping are present, but the cervix remains closed. This condition does not always lead to a miscarriage and can be managed with medical attention.
Step-by-step explanation:
A threatened abortion refers to a condition during pregnancy where there are signs that a miscarriage might take place. In such a case, statement A is true: Vaginal bleeding and cramping are present, but the cervix remains closed. This means that while there might be discomfort and even some bleeding, the cervix has not dilated (opened), which would be a step towards an actual miscarriage.
It's important to note that conditions such as a threatened abortion do not always lead to a miscarriage and can be managed with medical attention, rest, and in some cases medication. If any symptoms of a potential miscarriage occur, they should be addressed with a healthcare provider immediately.
