## Core Concept
A Community Health Centre (CHC) is a type of healthcare facility in the Indian healthcare system, serving as a referral center for Primary Health Centres (PHCs) and Community Health Centres. The infrastructure and capacity of CHCs are designed to provide specialized care.

## Why the Correct Answer is Right
The correct answer states that a CHC has 30 beds. According to the guidelines and norms set by the Indian government for health infrastructure, a Community Health Centre is indeed equipped with 30 beds. This capacity is part of the norms to ensure that CHCs can provide adequate in-patient services and act as a referral base for the PHCs.

## Why Each Wrong Option is Incorrect
- **Option A:** 10 beds - This number is too low for a CHC and aligns more with the bed capacity of a Primary Health Centre.
- **Option B:** 20 beds - While closer, it still does not meet the standard requirement for a CHC.
- **Option D:** 40 beds - This is more than the standard norm for a typical CHC.

## Clinical Pearl / High-Yield Fact
A key point to remember is that CHCs are equipped with 30 beds and serve as referral centers for PHCs. They are also supposed to provide specialized care, including obstetrics and gynecology, pediatrics, and surgery.

## Correct Answer: C. 30 beds
