## Core Concept
The question pertains to demographic and reproductive health indicators, specifically those that involve reproductive women. These indicators are crucial in epidemiology and public health for assessing the health and reproductive status of a population.

## Why the Correct Answer is Right
The correct answer involves identifying which of the listed indicators specifically relate to reproductive women.
- **Birth Rate (a)**: Also known as the crude birth rate, it measures the number of live births per 1,000 people per year. While it does involve births, it is not specific to reproductive women.
- **General Fertility Rate (G.F.R) (b)**: This measures the number of births per 1,000 women of reproductive age (usually 15-44 or 15-49 years) per year. It directly involves reproductive women.
- **Total Fertility Rate (T.F.R) (c)**: This is the average number of children a woman would have in her lifetime based on the current fertility rates of a population. It directly involves reproductive women.
- **Maternal Mortality Rate (d)**: This measures the number of deaths among women due to complications of pregnancy or childbirth per 100,000 live births. It specifically involves reproductive women.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incomplete and cannot be evaluated.
- **Option B:** This option is missing details but if it does not include all correct indicators (b, c, d), it is incorrect because it misses one or more relevant indicators.
- **Option C:** Similarly, if this option does not encompass (b, c, d), it is incorrect for missing relevant indicators.
- **Option D:** Without specifics, if it includes incorrect indicators or misses (b, c, d), it would be incorrect.

## Clinical Pearl / High-Yield Fact
A key point to remember is that **GFR, TFR, and Maternal Mortality Rate** are specific indicators that directly relate to the reproductive health of women. These indicators are vital for public health planning, especially in areas related to maternal and child health.

## Correct Answer: C.
