Which C-section indication relates to a risk of fetal distress?

Active maternal infection is indeed a valid indication for a C-section that can relate to a risk of fetal distress. When an active infection is present, especially if it could lead to sepsis or affect the fetal environment, the well-being of the fetus might be compromised. Conditions like chorioamnionitis, which is an infection of the amniotic fluid and membranes, can cause significant concern for fetal health, potentially leading to fetal distress.

In such cases, delivering the baby via C-section may be the best course of action to prevent further complications related to the infection and to safeguard the fetus's health. Delivering a baby in the presence of active maternal infection can help mitigate risks and ensure better outcomes for both the mother and the baby.

In contrast, the other options provided may not necessarily present immediate or direct risks of fetal distress in the way that active maternal infection does. Pre-term labor might result in delivery before the fetus is fully developed, but it does not inherently indicate fetal distress. Normal fetal growth signifies that the fetus is developing appropriately, which doesn't relate to fetal distress either. Maternal anxiety, while it can affect the mother's state and potentially influence labor, does not directly correlate with fetal distress in the same way that an infection does
