## **Core Concept**
The Millennium Development Goals (MDGs) were eight international development goals established by the United Nations (UN) in 2000. These goals aimed to address various global issues such as poverty, education, and health by a specific target year.

## **Why the Correct Answer is Right**
The MDGs were set to be achieved by the year 2015. This timeline was established to create a sense of urgency and focus global efforts on achieving these critical development objectives within a 15-year timeframe, from 2000 to 2015.

## **Why Each Wrong Option is Incorrect**
* **Option A:** 2010 - This is too early for the MDGs to be achieved, as it does not allow sufficient time for implementing and impacting large-scale changes globally.
* **Option B:** 2020 - This is beyond the original target year set for the MDGs. Although progress was made, the goals were specifically aimed to be accomplished by 2015.
* **Option D:** 2030 - This aligns with the Sustainable Development Goals (SDGs) that succeeded the MDGs, not the target year for the MDGs themselves.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the MDGs were replaced by the Sustainable Development Goals (SDGs) in 2015, which continue the effort to address global challenges with new targets and indicators.

## **Correct Answer:** . 2015
