## Core Concept
Urban health posts are integral components of the healthcare system in urban areas, providing various health services to the population. They are often linked with hospitals to ensure comprehensive care, including specialized services.

## Why the Correct Answer is Right
The correct answer, **Urban Health Centre (UHC)**, is attached to a hospital for providing specialized services such as sterilization, Medical Termination of Pregnancy (MTP), and referral services. UHCs are designed to offer a range of health services, including family planning and reproductive health services, which align with the mentioned services.

## Why Each Wrong Option is Incorrect
- **Option A:** (Sub Centre) - This is the most peripheral and first contact point between the primary healthcare system and the community. It does not typically provide specialized services like sterilization and MTP.
- **Option B:** (Primary Health Centre) - While it provides a range of services, it is more focused on basic healthcare and may not have the specialized facilities for sterilization, MTP, and advanced referral services.
- **Option D:** (Community Health Centre) - Although it is a referral site for PHCs and provides more specialized care, the question specifically mentions a setup attached to a hospital for services like sterilization, MTP, and referral, making UHC a more precise fit.

## Clinical Pearl / High-Yield Fact
A key point to remember is that Urban Health Centres (UHCs) play a crucial role in urban health care delivery, especially in providing family planning services, maternal and child health services, and serving as a referral point for more specialized care.

## Correct Answer: C. Urban Health Centre.
