## **Core Concept**
The Mental Health Act is a legislation that governs mental health care and treatment in a country. It outlines the rights of individuals with mental illness, the responsibilities of healthcare providers, and the procedures for involuntary hospitalization and treatment. The Act aims to protect the rights of people with mental illness while ensuring they receive proper care.

## **Why the Correct Answer is Right**
The Mental Health Act of 1987 in India, for instance, was enacted to consolidate and amend the law relating to the treatment and care of mentally ill persons. It came into effect on April 1, 1990, replacing the earlier Lunacy Act of 1912. This Act emphasizes the importance of providing care and treatment in a manner that respects the rights of the mentally ill.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 1950 - This is too early for the Mental Health Act in many countries, including India, as it does not align with the known legislative timeline for mental health reforms.
- **Option B:** 1970 - Although there were discussions and attempts to reform mental health legislation around this time, it does not correspond with the actual enactment of the Mental Health Act in many jurisdictions.
- **Option D:** 1990 - This option might seem plausible because it aligns with the year the Act came into effect in some countries. However, the actual year of passing the Act is usually a couple of years before it is implemented.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the Mental Health Act varies by country, but it generally aims to provide a legal framework for the compulsory admission, treatment, and discharge of people with a mental illness. Knowing the specific year of enactment for your country or region is crucial.

## **Correct Answer:** C. 1987
