**Core Concept:** Committees and initiatives related to healthcare infrastructure development.

**Why the Correct Answer is Right:**
The correct answer is **Facility Planning and Design (FPD) Committee**. The FPD Committee is a part of the Indian Public Health Standards (IPHS), which is a program aimed at improving the quality of healthcare services in India. This committee focuses on developing guidelines for the planning, design, and construction of health facilities that cater to a specific population size.

In this context, the committee focuses on designing health centers that can serve a population ranging from 10,000 to 20,000 people. This ensures that the facilities are appropriately sized and equipped to meet the healthcare needs of the targeted population.

**Why Each Wrong Option is Incorrect:**
A. **Infrastructure Planning and Development (IPD) Committee**: While IPD Committee is involved in overall planning and development of health facilities, it doesn't specifically focus on designing health centers for specific population sizes.

B. **Facility Management (FM) Committee**: FM Committee is responsible for managing existing health facilities, ensuring their maintenance, and improving their performance, rather than designing new ones.

C. **Facility Standards Committee**: Facility Standards Committee focuses on setting standards for the quality and performance of health facilities rather than determining the size of the facilities based on population.

D. **Technical Standards Committee**: The Technical Standards Committee sets guidelines for the technical aspects of health facilities, but it doesn't specifically deal with designing health centers for specific population sizes.

**Clinical Pearl:**
Understanding the role of different committees in healthcare planning is crucial for medical professionals. Being aware of these committees can aid in making informed decisions about the appropriate healthcare facility and its resources allocation based on the population served.

**Correct Answer:** Facility Planning and Design (FPD) Committee
