## Core Concept
Maternal death is defined as the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management (WHO). The causes of maternal death can be broadly categorized into direct, indirect, and other (including accidents).

## Why the Correct Answer is Right
The correct answer, , is not a cause of maternal death. Typically, causes of maternal mortality include direct causes such as hemorrhage, eclampsia, obstructed labor, and infection, as well as indirect causes like cardiovascular diseases, diabetes, and malaria.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the **four delays** in maternal healthcare can contribute to maternal mortality: delay in deciding to seek care, delay in reaching a healthcare facility, delay in receiving appropriate care at the facility, and delay in referring to a higher level of care. Understanding these delays can help in strategizing interventions to reduce maternal mortality.
